HPCC-10794 - Sasha search fails to find some workunits

If a workunit search has a pattern which includes a time, Sasha
incorrectly normalizes the date/time format of the workunit,
introducing a spurious '-' and in so doing, fails to find the
workunits being searched for.

HPCC-10595 Don't display ecl-packagemap-validate success on warnings

Other warnings prevent the output of "validation successful" but warnings
about files that are unmapped or not in dfs currently don't prevent that
message.  Make all warnings behave consistently in this regard.
