screen-cast/src: Remove follow up timeout source on disable

Browse source 
We failed to remove the timeout source when disabling, meaning that if a
follow up was scheduled, and shortly after we disabled the source, the
timeout would be invoked after the source was freed causing
use-after-free bugs.
