Fix OOM error in BsaValidation (#2813)

Error happened in the case that an unblockable name reported with
'Registered' as reason has been deregistered. We tried to check the
deletion time of the domain to decide if this is a transient error
that is no worth reporting. However, we forgot that we do not have
the domain key in this case.

As best-effort action, and with a case that rarely happens, we decide
not to make the optimization (staleness check) in thise case.
