Revert " Audio: SetForceUse config check in AudioService"

This reverts commit 0af88afe6dc16760b57afa74ca42e40fbe6ff9cf.

- During playback over BT using the Google Play Music app,
  if BT is disconnected through the app and playback is resumed,
  it continues over BT and not the speaker.
- The original commit forces playback to continue over BT
  although it is disconnected.
- Reverting the commit fixes this issue and the issue
  addressed by the commit is also not observed after reversion.

HeadsUp: Only remove heads up if attached to window

Attempting to remove mHeadsUpNoficiationView from the window manager
when it is not currently attached will throw an IllegalArgumentException
so we check if it is attached and if so remove it, otherwise carry on.
