Fix order of commands in test for removing topology segments
test_topology_updated_on_replica_install_remove from the beginning used
invalid sequence of commands for removing a replica.
Proper order is:
master$ ipa server-del $REPLICA
replica$ ipa-server-install --uninstall
Alternatively usage of `ipa-replica-manage del $replica` instead of
`ipa server-del $replica` is possible. In essence ipa-replica-manage
calls the server-del command.
At some point there was a plan to achieve uninstalation only through
`ipa-server-install --uninstall` but that was never achieved to this
This change also removes the ugly wrapper which makes test collection
fail if no environment config is provided (i.e. replicas cannot be
$ pytest --collect-test ipatests/test_integration
