osd/PrimaryLogPG: fix on_local_recover crash on stray clone
If there is a stray clone (one that does not appear in the SnapSet) and
we do any sort of recovery on it the OSD will crash. Log an error instead
but continue.
This addresses a problem where a cluster has both (1) an unexpected clone
and (2) the clone is not present on all replicas. Doing repair on that
PG will both not fix the unexpected clone and also cause the remaining
OSDs to crash trying to recover it.
Include a test.
