aggregator: Wake up source pad in PAUSED<->PLAYING transitions

Browse source 
When going to PLAYING we will now have a clock and can stop waiting on
the condition variable and instead start waiting on the clock if
necessary for the current configuration.

In the other direction when going to PAUSED the clock might have
disappeared and we might need to wait on the condition variable again
instead.
