 Invalidate term query caches when setting or deleting term relationships.

 Prior to 4.7, term relationships - as set by `wp_set_object_terms()` or
 `wp_remove_object_terms()` - did not affect the term query cache. The
 introduction of the 'object_ids' parameter in 4.7 means that the query
 cache must be aware of object-term relationships. As such, the
 'last_changed' incrementor is now invalidated when term relationships
 are modified.

 This bug only reared its head when delaying term counting, because term
 counting performs its own term query cache invalidation.

 Props mboynes.
 Fixes #40306.
