Backed out changeset 7a58581d842c
This changeset breaks a number of CW tests, which depends on pre add hooks. I'm
backing it out, so that we can start the need-for-speed sprint with green tests
(and possibly rework this changeset)
# 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('state_of')
sync_schema_props_perms('transition_of')
