splitmuxsink: Fix race in unit tests. Add fragment-id to messages

Browse source 
Publish fragment-id in the messages that splitmuxsink and splitmuxsrc
send, so when they are received out of order (due to async finalization,
for example), they can still be identified / ordered correctly.

Fix a race in the splitmuxsink unit test where messages might be
received out of order
