testing: check result of "item already exists" during insert

The new testInsertTwice checks what the backend does when the same
item already exists in the database. This is only done for test data
which has a UID (i.e. for calendar data, but not for contacts). This
test exercises the code which previously failed with 412 "Precondition
Failed" in the CalDAVMemo backend.
