[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).
# type attribute might already be there if migrating from
# version < 3.5 to version >= 3.5.3, BaseTransition being added
# in bootstrap_migration
if versions_map['cubicweb'][0] >= (3, 5, 0):
add_attribute('BaseTransition', 'type')

sync_schema_props_perms('transition_of')
