Title: #128: Fix group renaming issue when "id_provider = ldap" is set

"""
BTW I am not sure whether fix is sufficient. base on comment https://github.com/SSSD/sssd/pull/128#issuecomment-325825877 "sss_cache" was called which invalidates entries + memory cache

But there were some bugs where people noticed "corrupted" memory cache after renaming groups. And I doubt they called `sss_cache` for invalidating entries.

It would be good to check that use-case as well. I will check myself on Friday if nobody else has a time.
Removing accepting label before such investigation.
