title: Issue with ConstraintLayout and TextView wrap_content
body: <p>Since I have updated to Android Studio 2.2 and start using <code>ConstraintLayout</code> with new UI Builder there is a problem, that I can't solve.</p>
  
  <p>I have a simple layout with <code>ImageView</code> and <code>TextView</code> to the right of <code>ImageView</code>. Text in <code>TextView</code> updates dynamicaly from server (I don't know exactly length of this text). I want to <code>TextView</code> use all free space between <code>ImageView</code> and right side of screen. Earlier with <code>RelativeLayout</code> I used 
      <code>TextView</code> <code>android:layout_width="wrap_content"</code> 
  and it worked:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;RelativeLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;ImageView
          android:id="@+id/imageView"
          android:layout_width="116dp"
          android:layout_height="178dp"
          android:layout_alignParentLeft="true"
          android:layout_alignParentStart="true"
          android:layout_alignParentTop="true"
          android:layout_marginLeft="16dp"
          android:layout_marginTop="16dp"
          tools:src="@drawable/pets"/&gt;
  
      &lt;TextView
          android:id="@+id/textView"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_alignTop="@+id/imageView"
          android:layout_marginLeft="16dp"
          android:layout_marginRight="16dp"
          android:layout_toEndOf="@+id/imageView"
          android:layout_toRightOf="@+id/imageView"
          tools:text="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque molestie tincidunt mi a gravida. Aenean faucibus a sapien ut consequat. Praesent sed placerat quam."/&gt;
  &lt;/RelativeLayout&gt;
  </code></pre>

  <p>But when I use ConstraintLayout, there is no textwrap and TextView is going out of screen.</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;android.support.constraint.ConstraintLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:app="http://schemas.android.com/apk/res-auto"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;ImageView
          android:id="@+id/imageView"
          android:layout_width="116dp"
          android:layout_height="178dp"
          android:layout_marginLeft="16dp"
          android:layout_marginTop="16dp"
          app:layout_constraintLeft_toLeftOf="parent"
          app:layout_constraintTop_toTopOf="parent"
          app:srcCompat="@drawable/pets"/&gt;
  
      &lt;TextView
          android:id="@+id/textView"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_marginLeft="16dp"
          android:layout_marginTop="16dp"
          android:ellipsize="none"
          android:text="Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque molestie tincidunt mi a gravida. Aenean faucibus a sapien ut consequat. Praesent sed placerat quam."
          app:layout_constraintLeft_toRightOf="@+id/imageView"
          app:layout_constraintTop_toTopOf="parent"/&gt;
  &lt;/android.support.constraint.ConstraintLayout&gt;
