Summary [MSE][GStreamer] Gracefully fail on invalid non-first initialization segment
Alicia Boya García

In normal operation of AppendPipeline, except during tear down, qtdemux never removes a pad. Even if a new initialization segment is appended, the pad is reused. There is an exception though: when the new initialization segment has an incompatible set of tracks. This is invalid under the MSE spec and should produce an error, but in this case this was making an assertion fail -- in particular by sending an EOS to the to-be-removed pad, which AppendPipeline doesn't expect. This patch changes the assertion with graceful error handling for that error. Fixes media/media-source/media-source-seek-detach-crash.html
