QueueViewController: Fix selection of currently playing media and improve the animation
This merge request brings a fix to:
- The selection of the currently playing media that now starts the playback again.
- Touching the drag indicator image view of the cell that does not trigger the cell selection anymore either.
This is a fix of a regression introduced with !344 (merged).
This merge request also brings a fix the reorganization of the play queue:
- The cells are now properly placed even if the gesture ends outside the bounds of the play queue.
- The animation of the currently playing cell is properly reloaded after being moved.
The scroll view is disabled for the currently playing cell without disabling the user interaction of the entire cell.
Closes #1758 (closed)
