Title:
  When calling Playlist.clear() onMediaRemoved is triggered for each
  track that is removed

Status in Canonical System Image:

Status in media-hub package in Ubuntu:

Bug description:
  When calling Playlist.clear() onMediaRemoved is triggered for each
  track that is removed, causing slowdown in the music-app's current
  implementation of storing the queue.

  What happened:
  1) Start the music-app
  2) Click on a track to create a queue
  3) From the header actions click "Clear queue"
  4) Observe that for each track a onMediaRemoved signal is emitted

  What I expected to happen:
  At step 4) for a single onMediaRemoved for the whole range is emitted

  A diff [0] for the music-app, so you can see the onMediaRemoved calls.
