[midPoint] - SciptedSQL connector misshandling inherited roles deletion

Hi Radovan. It worked for ActiveDirectory connector but didn't for the
ScriptedSQL. We have added an echo at the beginning of each groovy scripts
printing the action and the object class received and It only receives an
ADD_ATTRIBUTE_VALUE of the value that the user already had. There is no
REMOVE_ATTRIBUTE_VALUE so I guess the issue is on the connector this time.
I have an isolated set of resource, meta role and role to reproduce the
issue. You can download it from here
<https://dl.dropboxusercontent.com/u/9319179/ScriptedSQLTest.zip> if you
want. The main difference with the Active Directory resource is in the
association: subjectToObject vs objectToSubject. Do you think the problem
could be there ? I'll try it.

I guess it would be helpful add this info of tolerant attribute on this
page: https://wiki.evolveum.com/display/midPoint/Entitlements.
