Fix "incremental check" mode of consistency check alarm

The way consistency check select documents to check at each run when running incremental mode, consistency seems to have issues which leads to documents not checked sometimes.

I noticed two reasons:

• When Zope runs with a timezone that is not UTC, the date comparison to find new documents compares a date in zope local timezone with a timestamp in mysql timezone. First fix is to pass a date to catalog, so that catalog convert it to the catalog timezone (it's a mistake to pass a date as string when using catalog programmatically). Second fix seem that we seem to need to configure mariadb to use UTC by default.
• alarm.getLastActiveProcess does not return the latest active process when alarm is executing activeSense so we need to pass include_active=True in this case.
