Subject: [PATCH] Fix edge case in HlsSampleSource.

1. prepare() needs to load a TsChunk to actually prepare the source.
2. Source is prepared, but no tracks are enabled (this is why it's
   an edge case - no-one is likely to be doing this!).
3. The TsChunk load completes.

We should not load additional chunks in this case.
