confusing certificate warnings
Bug description
I have an account at jabber.ccc.de and they use a cacert certificate.
Due to that, some cert warnings are expected, but there is an additional issue:
Gajim first warns about the root certificate of cacert (and lets you confirm the fingerprint of the root cert).
Then it warns again (in a rather alarming way) that the fingerprint has changed and lets you confirm the fingerprint of the jabber.ccc.de cert.
See screenshot.
Steps to reproduce
Try with any jabber.ccc.de account (or anything else based on a cacert account).
