A patch from Nicolas Malin for "fieldGroup will ignored if all contains fields are ignored" https://issues.apache.org/jira/browse/OFBIZ-5136

When you have a fieldGroup that contains fields with use-when attribute, if all fields aren't use, the fieldGroup is empty.
Improvment: to not display the field group
