title: Applying a theme to AlertDialog Builder causes the title to not work correctly
body: <p>I am attempting to add a title to my AlertDialog Builder. When I add the theme, my title gets moves into the selection area. 
  <br>
  Here is the first example:</p>
  
  <pre><code>    classificationButton.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              AlertDialog.Builder builder = new AlertDialog.Builder(
                      new ContextThemeWrapper(mContext, android.R.style.Theme_Holo_Dialog) );
                      //building my selection options
                      builder.setItems(classificationList, new DialogInterface.OnClickListener() {
                          public void onClick(DialogInterface dialog, int which) {
                              String desiredClassification = classificationList[which];
                              if ( !getClassification().equals(desiredClassification) ) {
                                  CallsignContract.updateClassification(desiredClassification, mContext);
                                  setClassification(desiredClassification);
                                  classificationButton.setText(desiredClassification);
                              }
                          }
                      });
                      builder.setTitle(R.string.classification_alert_header)
                              .create().show();
          }
      });
  </code></pre>
  
  <p>This is the result.

  On this second attempt, I create a alertdialog from the builder and give that a title. The result is the correct title, but the title appears again in the selection area.</p>
  
  <pre><code>        classificationButton.setOnClickListener(new View.OnClickListener() {
          @Override
          public void onClick(View v) {
              AlertDialog.Builder builder = new AlertDialog.Builder(
                      new ContextThemeWrapper(mContext, android.R.style.Theme_Holo_Dialog) );
                          //building my selection options
                          builder.setItems(classificationList, new DialogInterface.OnClickListener() {
                          public void onClick(DialogInterface dialog, int which) {
                              String desiredClassification = classificationList[which];
                              if ( !getClassification().equals(desiredClassification) ) {
                                  CallsignContract.updateClassification(desiredClassification, mContext);
                                  setClassification(desiredClassification);
                                  classificationButton.setText(desiredClassification);
                              }
                          }
                      });
              AlertDialog alertDialog = builder.create();
              alertDialog.setTitle(R.string.classification_alert_header);
              alertDialog.show();
          }
      });
