Bust term query cache when modifying term meta.

Browse Source 
The 'last_changed' incrementor is used to invalidate the `get_terms()` query
cache. Since `get_terms()` queries may reference 'meta_query', changing term
metadata could change the results of the queries. So we invalidate the cache
on add, delete, and update.

See #10142.
