Fix Spec11 domain check (#1105)

* Fix Spec11 domain check

We should be checking to see if there are _any_ active domains for a given
reported domain, not to see if _the_ domain for the name is active.

The last change caused an exception for domains with soft-deleted past domains
of the same name.  The original code only checked the first domain returned
from the query, which may have been soft-deleted.  This version checks all
domain records to see if any are active.

* filter().count() -> anyMatch()
