[sync] SyncML improvements

[Martin Middeke]

Hi...

i recognized another Problem for now:

(start with an empty turba adressbook)

1) add a contact to my PHONE
2) SYNC
=> TURBA and PHONE are equal

3) change contact in PHONE
4) SYNC
=> TURBA and PHONE are equal

5) change contact in TURBA
6) SYNC
=> TURBA and PHONE are NOT equal


reapeat step 3 and 4 works like a charm! i tried the test with the
HOMEPHONE Field
