+- fixed migrations of permissions that can lead to inconsistency.
+  Some users sent feedback that after upgrading from older versions issues with updating
+  default permissions occured. RhodeCode detects that now and resets default user
+  permission to initial state if there is a need for that. Also forces users to set
+  the default value for new forking permission.
