[Vobject] difference between handling of 2.1 and 3.0

There's a tree of behaviors that get assigned to objects when they get
parsed, depending on what component/version you're using (so iCalendar
has its set of behaviors, and vCard another).

The system *ought* to fall back to VCARD 3.0 if no behavior is found for
VCARD 2.1, but it looks like that isn't working, I'm not sure why.
Thanks for pointing it out.  I'm not sure when I'll get around to fixing
that, but as usual, Patches Welcome :)

Sincerely,
Jeffrey
