[migration] Improve update of in-memory schema during 3.18 CWAttribute.defaultval change We weren't updating the schema properly so a bunch of structures still had the old rdef with 'String' as object. That caused failures to add new attributes later in the migration as their default value would be a Binary object but the schema would expect a String. Closes #3683640

for source in rql('CWSource X WHERE X type "ldapuser"').entities():
    config = source.dictconfig
    host = config.pop('host', u'ldap')
    protocol = config.pop('protocol', u'ldap')
    source.cw_set(url=u'%s://%s' % (protocol, host))
    source.update_config(skip_unknown=True, **config)
