Fix #134293: Compositor crash after adding view layer

Browse Source 
The compositor crashes when the active viewer layers is deleted and
replaced by a new layer. That's because the depsgraph of the compositor
still references the old view layer. To fix this, we need to update the
view layer of the compositor if it changed since it was last created.
