Eleven: Fix crash with enabled visualizer but missing permission

* When the visualizer was enabled but the permission wasn't granted,
  swiping the visualizer into view would close the app
  * This happens since the request code for both permission requests
    used to be equal
  * move both codes to PreferenceUtils and give them distinct numbers
* In settings activity, the switch state didn't represent when it was
  enabled but the permission denied (either directly after enabling or
  also later, via Settings app)
  * Fixed by setting the check-state programmatically
* AudioPlayerFragment: Would spam the logs with repeated requests since
  HomeActivity's onWindowFocusChanged would be called after each request
  when we denied the permission
  * introduce a variable mIgnoreAfterRequest to ignore a second
    setVisualizerVisible() call, indirectly triggered by
    requestRecordAudio
