tests: videodecoder: check that segment events are not dropped

Browse source 
Adds a test that simulates a scenario where the first buffers after
a segment can't be decoded and the decoder asks for those frames
to be released. The videodecoder base class should make sure that
the events attached to those first buffers are pushed even if the
buffers aren't going to be.
