Title: #85: SYSDB: Removing of sysdb_try_to_find_expected_dn()

"""
I pushed new version of the patch set. I addressed @sumit-bose notes, I hope in right manner.

Unfortunately ```test_user_is_from_another_domain()``` doesn't work in expected way. My opinion is that user from another_domain shouldn't be selected. I would like to test negative case.

I found out that  function ```sdap_domain_get_by_dn()``` doesn't return right domain even other_domain is in ```opts```.
