eventEngine does not work in NAV 3.2.0

The eventEngine inadvertently uses an inccorrect way of discovering the
maintenance status of devices. It relies on the tables of the old
messages/maintenance subsystem, which was replaced in NAV 3.2.0.

The old tables have been dropped, cause the eventEngine's device plugins to
throw SQLExceptions when attempting to collect device data. The
eventEngine consequently fails to see any of the devices in the NAVdb and
will not function properly for most events.
