Re-opening so we don't forget to fix the API breakage.

thinking about it some more, the "fix" was totally bogus: create() and 
modify() return the (IMAP) backend uid of the object in question: Wild 
guess: This change will break ActiveSync for Kolab + notes.

The way the code was changed from my original implementation breaks
the API contract of Kolab_Storage:

create() and modify() might return the uid of the Kolab object *or* 
true if the used backend does not support it.

IMHO it's better to use my original implementation of this fix.
That would also give proper credits in the git commit history...

Hi,

the Kolab backend in "master" and FRAMEWORK_5_2 is currently broken:
"Add" and "modify" does not work.

Attached patch fixes the issue.

Cheers,
Thomas
