ipatests: use whole date for journalctl --since

When a test is executed around midnight and is checking the
journal content with --since=date, it needs to specify the
whole date (with day and time) to avoid missing entries.

If for instance --since=23:59:00 is used and the current time is
now 00:01:00, --since=23:59:00 would refer to a date in the
future and no journal entry will be found.
