Error mapping GST state

[trygveaa]

I played around with stuff adding and playing tracks etc. Not sure what triggered this.

Traceback (most recent call last):
  File "/home/trygve/dev/mopidy/mopidy/mopidy/audio/actor.py", line 210, in on_message
    self.on_playbin_state_changed(old_state, new_state, pending_state)
  File "/home/trygve/dev/mopidy/mopidy/mopidy/audio/actor.py", line 260, in on_playbin_state_changed
    target_state = _GST_STATE_MAPPING[self._audio._target_state]
KeyError: <enum GST_STATE_READY of type GstState>

Am I right that this is a duplicate of #1222?

Does this lead to Mopidy being unusable, or does everything still seem to work?

[trygveaa]

Yes, this is a duplicate. I hadn't seen/didn't remember #1222 when opening this. @adamcik said this on IRC after I opened this:

11:46:50 <+adamcik> trygveaa: #1430 is kinda a dupe if race free audio. At least the same error is what triggered that bug
11:51:38 <+adamcik> But we might just want to solve 1430 with a workaround and use the other issue to track a systematic fix of audio with respect to this

I think everything still worked after this happened.

[adamcik]

Quick fix is just to consider READY == PAUSED, it's not correct, and might show some weird results, but it won't break anything. So it's better than having these random errors.

This occurs in #1722 also.
