[REQUIRED] Reproduction steps

I cannot reliably reproduce this issue, but I suspect that it might be caused by multiple calls to ConcatenatingMediaSource.addMediaSouce() Rough application flow is as follows...

• Add single MediaSource to a ConcatenatingMediaSource
• Prepare player with that ConcatenatingMediaSource
• Once the timeline has changed set speed and playWhenReady to true
• Add multiple (variable number of) additional MediaSources to the ConcatenatingMediaSource

This issue was already fixed by a recent change.

This change may still be some way away from being part of a release. I added a smaller fix to 2.11.1 too
