fix(hybridcloud) Remove externalactor.actor_id (#60548)

This field was removed from django state a few months back in #56534
This field is now causing issues in deletions as foreign key constraints
are preventing records from being deleted. Removing the unused column
seems like the most efficient solution.

Fixes SENTRY-163E
