QueueViewController: Queue Remove Media Enhancements

This Merge brings a UI Update and handles some corner cases.

Corner cases

• Removing the currently playing media from the queue did not change the playback and the queue collection view wasn't being updated correctly.
• Removing all media from the queue did not stop the playback and produced an empty collectionView.

Enhancements

• Adding a remove button to only queue cells makes removing media easier and clearer than the scroll-to-remove method.
• Handling removing the currently playing media and changing the playback to the proper media item due to the index and playing mode.
• Ensuring that playback is stopped when the queue becomes empty after removing all media.
