* Fix SLM check for restore in progress

This commit fixes the check in SLM where the `RestoreInProgress`
metadata was checked for existence. Rather than check existence we
should instead check the `isEmpty` method. Prior to this, a successful
restore for a repository that used SLM retention would prevent SLM
retention from running in subsequent invocations, due to SLM thinking
that a restore was still running.

* Fix 7.x-isms
