Fixed package path in testsetup.

The testrunner wronlgy searched the complete project, so also the `src` directory for tests, which end in import errors. With this change the runner only runs test from the opengever.core package.
Fixed backref name of the groups_user join table.

See https://github.com/4teamwork/opengever.ogds.models/pull/4 for more details.
Added missing kgs inclusion.

The commit #9cba578e9105ab15ab20f58179e4563db9786ca9 dropped the
opengever-zug kgs inclusion, which is right, but it dropped the
complete inclusion of the kgs version. The standard opengever
version pinings are necessary.

Removed IMailInAddress behavior. Not needed any more with ftw.mail 2.0.
Provide an IntIdResolver adpater to generate Dossier Mail-In addresses

based on IntIds, and use it instead of the old implementation.
Removed og.mail IMailSettings registry interface (now done in ftw.mail).

Added upgrade step to migrate settings to ftw.mail's IMailSettings and
remove old og.mail IMailSettings.
Hide standard ftw.mail mail-in viewlet (we display the mail address in the byline).
Update mail related tests.

- Mails can't be added inside tasks. Neither directly nor via mail-in.
- Expected mail domain should be set in test itself
Use ftw.mail from source until we create a KGS that uses >= 2.0.
