IP Device info crashes

[Morten Brekkevold]

The IP Device Info beta preview in NAV 3.4.0 crashes out of the box.

Apparently, there is an error in the Django models: The module class
contains a "community_suffix" field which doesn't exist in manage.sql. It
did, however, exist on the development database where the IP Device Info
tool was developed, which is probably why the model is faulty.

The Django DEBUG setting is set to False by default in the 3.4.0 release,
which causes the IP Device Info tool to crash with this, very little
informative, traceback:

With Django's DEBUG setting set to True, this error appears instead:

This is the actual error reported when Django's DEBUG setting is set to
True.

Fixed in changeset 28397e6636dc on the default branch. Should make it
into NAV 3.4.1.

Vidar Stokkenes reports another similar error with the vendor.enterpriseid
field, which has also appeared due to introspecting an experimental/devel
database.

Followup fix in changeset b5fc18a21caf, committed to default branch. Will
be part of NAV 3.4.1.
