Winterfell, vanilla test just hangs because of guam

[tpokorra]

running kolab sync in debug mode shows:

LANG=C kolab -d 9 sync 2>&1 | tee kolab-sync.log
2016-06-14 07:36:59,844 pykolab.imap WARNING Could not connect to Cyrus IMAP server 'imaps://localhost:993'
every 10 seconds

actually, the reason is that guam is not happy.

journalctl -u guam shows many errors like this:

Should I add a separate test for guam?

I reported this as a bug: https://git.kolab.org/T1305
