Description of problem:
When trying to remove scoped role with active "include-all" option an "Failed to remove TestRole" error is thrown even though role is deleted. This might be a consequence of unsuccessful attempt to remove role mapping

Following error can be seen in console
http://pastebin.test.redhat.com/167346

Steps to Reproduce:
1. Create new scoped role with active "include-all"
2. Try to remove the role previously created

Actual results:
Inconsistent access control configuration – role-mapping is left in configuration

Expected results:
Both role and it's mapping are removed
