Not stop playback when SimpleExoPlayerView.setPlayer(null)

[keima]

Thanks for developing very useful library.

A description of the issue.

Not catching STATE_ENDED and not stop and keep moving position (player.getCurrentPosition()'s value) when position is exceeded to MediaSource's duration at specific condition.
(Sorry I'm just trying HlsMediaSource so I don't know other MediaSource)

I doubt that my project has two SimpleExoPlayerView and switch active view ( on the one hand is view#setPlayer(player) , on the other hand is view.setPlayer(null) ).
But I reproduced issue when single SimpleExoPlayerView and setPlayer(null) after setPlayer(player) and prepare/play HLS source.

Steps describing how the issue can be reproduced, ideally in the ExoPlayer demo app.

This issue is not reproduce ExoPlayer demo app.
(demo app doesn't provide setPlayer(null))

I make sample app that able to set player instance and null.

How to reproduce:

1. Run sample app
2. Tap [1] Prepare button
3. Tap [2] setPlayer(player and show controller in SimpleExoPlayerView
4. Tap play button on SimpleExoPlayerView
5. (if you bored waiting 30mins, you can seek to about 29min30sec.)
6. Tap [3] setPlayer(null) before reach to 30min (about 1800000 milliseconds on debug text).
7. You will looking over-running currentPosition on debug text.

The version of ExoPlayer being used.

r2.2.0 (I occured r2.0.2, but reproduced at latest version).

@AquilesCanta
Could you answer a few question?

After investigating my implement above, I realized stream is stop little bit like buffering when setRendererDisabled(index, false) after setRendererDisabled(index, true).
(Not happened when setRendererDisabled(index, true) after false.)

I watching logcat during above situation, AdaptiveMediaSourceEventListener#onLoadStarted() and onLoadCompleted() are called but nothing called ExoPlayer.EventListener#onPlayerStateChanged().

I want to prevent "buffering" ( stop streaming little bit ), are you know any solution, or impossible?
