Fix back-updating from caldav -> tw

t add kalimera  # id: 1
tw_caldav_sync ...
t mod 1  kalimera2
tw_caldav_sync
\# on subsequent syncs, the item 'kalimera2' would update caldav->tw
because the description field was set in the former to "" and was unset
in the latter.

We're also not accounting the SYNCALL_TW_UUID in the identical keys to
compare since that exists in the caldav version but not in the TW one.
