Improve handling of template platforms when entity extraction fails (#37831)

Browse source 
Most of the the template platforms would check for
extract_entities failing to extract entities and avoid
setting up a state change listner for MATCH_ALL after
extract_entities had warned that it could not extract
the entities and updates would need to be done manually.
This protection has been extended to all template platforms.

Alter the behavior of extract_entities to return the
successfully extracted entities if one or more templates
fail extraction instead of returning MATCH_ALL
