Implemented ACTOR sub-field filtering (#11957)

This PR implements what's missing for ACTOR sub-field filtering,
filtering on the source sub-field was already working.

We can now filter on name sub-field. 

Since the sub-fields are different types and cannot be filtered both by
text, we consider that a simple filter on ACTOR is filtering on the
source, we have to go to advanced filter to have the name filter
sub-field.
