[server] fix repository initialisation
Changeset d753d6a6798f was breaking database creation. Dropping the
`config.creating` clause lead to trying to load the schema from database even in
creation mode. Conditional are a bit altered and reordered to prevent this to
happen.
from cubicweb.schemas.base import in_group, CWSourceSchemaConfig
# copy __permissions__ to avoid modifying a shared dictionary
in_group.__permissions__ = in_group.__permissions__.copy()
in_group.__permissions__['read'] = ('managers',)
cw_for_source = CWSourceSchemaConfig.get_relation('cw_for_source')
cw_for_source.__permissions__ = {'read': ('managers', 'users'),
'add': ('managers',),
'delete': ('managers',)}
