Enable and start oddjobd after ipa-restore if it's not running.

If after ipa-restore the service oddjobd is not running,
domain-level1 replica installation will fail during
ipa-replica-conncheck because this step is using oddjob
to start the process ipa-replica-conncheck on the master.

This patch fixes it. Also added regression test.
