Detaching and reattaching ExoPlayer at end state does not show last frame

If you let ExoPlayer play to the last frame of the video that frame will remain shown -- which is what we want.

While in that state if you detach the player view from the view hierarchy and re-attach it, however, you get a blank/black screen area rather than the last frame.

It seems that the "showing last frame" state should be retained/restored in this case.

(This issue is reproducible with 2.16.1, the latest ExoPlayer version at this time.)
