title: Ion sets the imageView height to a wrong value
body: <p>I dont know why this is happening: After loading the image with the Ion library, my image shows two white bars below and above image. I don't want to have that.</p>

  <p>My ImageView is displayed in a listview item. My adapter code looks like this:</p>
  
  <pre>
  if (node.getImageUrl() != null) {
      ivImage.setVisibility(View.VISIBLE);
      Ion.with(ivImage)
              .placeholder(R.drawable.anne_eli_icons_set_up_anne_eli_logo_530px)
              //.error(R.drawable.error_image)
              //.animateLoad(android.R.anim.cycle_interpolator)
              .animateIn(android.R.anim.fade_in)
              .load("http://app.anne-eli.at/" + node.getImageUrl().getUrlBig());
  
  
  } else {
      ivImage.setVisibility(View.GONE);
  }
  </pre>
  
  <p>My imageview layout like this:
  <code>
  &lt;LinearLayout ...
      &lt;ImageView
              android:id="@+id/fragment_appointment_list_item_article_iv_image"
              android:layout_width="match_parent"
              android:layout_height="wrap_content"
              android:src="@drawable/anne_eli_icons_set_up_anne_eli_logo_530px"
              android:background="@color/gray1" />
  &lt;/LinearLayout>
  </code></p>
  
  <p>Any ideas?</p>
