Fix T88666: Cryptomatte: EXR sequence does not update when scrubbing the timeline.

Cause is that initializing the cryptomatte session would reset the
current frame of an image sequence. The solution is to always use the
scene current frame so it resets to the correct frame.

This was a todo that wasn't solved after it landed in master.
Needs to be backported to 2.93.
