The attached totally untested patch changes sync_server's handling of
the case of "UPLOAD %d %d\r\n" as if it was UIDLAST and removes the
index_list->count == 0 test.  It's probably not the best way in
retrospect, but it's sitting around already written!  I'm thinking maybe
just check for count == 0 and run cmd_uidlast on the sync_client end
instead.
