Helps with #7853: Switch representation in bulk on selected objects

For non-active objects, match both ContextOfItems and
RepresentationIdentifier (e.g. 'Body', 'Axis') against
the active object's target representation. Previously only
ContextOfItems was compared, causing all objects sharing
the same parent context to be skipped incorrectly.

Also pass disable_opening_subtractions to core, which was
previously declared but never forwarded.
