[schema sync] Update repo._type_source_cache when renaming an entity (closes #2094470) When an entity type is renamed as part of a migration, it leaves stale entries in repo._type_source_cache, which makes subsequent operations on those entities fail (they look for the old entity name instead of the new one).
Ignore whitespace changes - Everywhere: Within whitespace: At end of lines:

a673d1d9a738 [diet] drop pre 3.6 API compatibility (but attempt to keep data cmopatibility). Closes #2017916
