pipeline: Handle rendering with disabled tracks

Browse source 
Summary:
The user might want to render only some media type of the timeline,
for example he wants to only render the audio part of the timeline.

It was failing as we were not connecting the track but were still trying
to 'render' it.

Depends on D153
