slapos_erp5: Add custom ERP5Type_asSecurityGroupIdSet

  We need to handle the order of source_project + function (sort) a non-standard way.

master/bt5/slapos_erp5/SkinTemplateItem/portal_skins/slapos_core/ERP5Type_asSecurityGroupIdSet.py

+def handleSort(_category_dict):
+  # Ensure that destination_project + function and source_project + function
+  # generates the same Security ID. This workarround is required because
+  # the value already arrives at this point pre-sorted on various locations
+  # and it is not possible to change since it is widely used.
+  if _category_dict.keys() == ['function', 'source_project']:
+    return ['source_project', 'function']
+
+  # Enforce return list in case
+  return list(_category_dict)
+
+return context.portal_skins.erp5_core.ERP5Type_asSecurityGroupIdSet(
+  category_dict=category_dict, key_sort=handleSort)
