Bug: 11563 Fix adding tags when using Kolab.

Kolab doesn't use the UID generated by Nag_Driver::add(), but
calculates it after, so we need to overwrite the UID that we send
to the tagger, or else it is tagged with the incorrect UID.

This was causing the kolab object to not be completly tagged until
the backend was synced with Horde again - essentially creating
orphaned rampage_object entries with the incorrect UID.
