Before capturing video, the Chamelium will always wait for the video
input to be stable (and perform the FSM if it was not). This means that
there is no need to explicitly do it beforehand.

When the receiver needs to be reset, the call will result in a timeout,
after which the follow-up call to capture the video will perform the FSM
that resets it. Skipping the explicit wait for video input stable allows
the Chamelium to perform the FSM directly, which saves valuable time.

Removing the associated call does not negatively impact the execution of
the CRC and frame comparison tests either.
