[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).
sync_schema_props_perms('CWSourceHostConfig', syncperms=False)
sql('INSERT INTO cw_source_relation(eid_from, eid_to) '
'SELECT e.eid,s.cw_eid FROM entities as e, cw_CWSource as s '
'WHERE s.cw_name=e.source AND NOT EXISTS(SELECT 1 FROM cw_source_relation WHERE eid_from=e.eid AND eid_to=s.cw_eid)')
