Omitting timestamp from msfconsole search output

SeeRM rapid7#8795

The disclosure date field in the results from the search command
where returning with a timestamp that was almost always 00:00:00 UTC. I added a bit of date time formatting to only
include the year (4 digit), month (2 digit), and day (2 digit)
in the following format: Y-m-d.  This date time formatting
applies to both searches conducted through the database instance
as well as searches performed without a database (slow search).
