pad-monitor: Move repeated caps to test only on sinkpads

Browse source 
Testing on source pads can lead to false positives when pads are
unlinked. The caps event is sticky and will be pushed again later
when another buffer/event is pushed, leading to an acceptable
situation to push the caps twice.
