+             When updating (not new install), as `share` module is not loaded yet, shared groups
+             are taken into account when getting the group list, resulting to a different
+             organisation of the `Sharing` category (booleans instead of a selection) and thus,
+             different virtual field names.
+             When applying then inheritance of the following view, the check of field names
+             failed due to these virtual field name missmatch.
+             This is only for databases updated between a6eac0f08ee9100d1a44a4068d4f580b1c7c4b2c
