Subject: [PATCH] Fix failure when a seek is performed with no enabled tracks

This issue affects ExtractorMediaSource only. We shouldn't
start loading in the case that we're prepared and have no
enabled tracks, since there's nothing that we need to load.
This was causing an assertion failure in startLoading.
