libobs: Fix race conditions

Browse Source 
Uses obs_source_get_ref on the sources enumerated in the tick_sources
function in obs-video.c to ensure a reference has been incremented
before calling that source's video_tick, and replaces an
obs_source_addref with obs_source_get_ref in the push_audio_tree
function in obs-audio.c to ensure that it cannot increment a source that
has already decremented its reference to 0.
