Grouped properties are not set to read-only

[Geert Bellekens]

Details:
When tagged values of a stereotype are grouped, they are no longer set to read-only with the rest of the properties.
Things like name, alias, or plain tagged values are read-only, but the grouped tags can still be edited.
This happens both with security based read-only or with version control based read-only


Steps to Reproduce:
-Create a BPMN Business process
-Set it to be read-only either by security or version control
-Try to change the property processType
-Notice that the property processType can still be changed, although the element is supposed to be read-only.
