ipatests: fix test_authselect
Before the code fix, install/uninstall on a config without
any authselect profile was not able to restore the exact
state but configured sssd profile instead.
Now that the code is doing a pre-install backup, uninstall
restores the exact state and the test needs to be updated
accordingly.
