title: FontFamily doesn't apply after upgrading support library
body: <p>I have a TextView:</p>
  
  <pre><code>&lt;TextView
          android:id="@+id/digits"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_centerHorizontal="true"
          android:layout_marginTop="13dp"
          android:translationY="5dp"
          android:text=""
          android:textSize="128sp"
          android:textColor="@color/white"
          android:fontFamily="fonts/Roboto-Thin.ttf"
  /&gt;
  </code></pre>
  
  <p>In my gradle file I used to have </p>
  
  <pre><code>dependencies {
      compile 'com.android.support:support-v4:19.1.0'
  }
  </code></pre>
  
  <p>Everything was great, TextView had proper font and typeface.</p>
  
  <p>But, when I changed support library version (so I can use new SwipeToRefreshLayout) to:</p>
  
  <pre><code>dependencies {
      compile 'com.android.support:support-v4:21.0.2'
  }
  </code></pre>
  
  <p>Then my TextView is not applying Robot Thin font, text is bolded. </p>
  
  <p>How come does it work this way? I think problem is only with Roboto-Thin, because other TextViews that have Roboto-Regular are working properly. Any ideas guys?</p>
