> List of UDT can't be updated properly when using USING TIMESTAMP
> Observe:
> {code}
> cqlsh:t360> CREATE TYPE fullname (
> ... fname text,
> ... lname text
> ... );
> cqlsh:t360> CREATE TABLE users (
> ... id text PRIMARY KEY,
> ... names list<frozen <fullname>>,
> ... phone text
> ... );
> cqlsh:t360> UPDATE users USING TIMESTAMP 1458019725701 SET names = [{ fname: 'fname1', lname: 'lname1'},{ fname: 'fname2', lname: 'lname2'},{ fname: 'fname3', lname: 'lname3'}] WHERE id='a';
> cqlsh:t360> select * from users;
> id | names | phone
> ----+--------------------------------------------------------------------------------------------------------------+-------
> a | [{lname: 'lname1', fname: 'fname1'}, {lname: 'lname2', fname: 'fname2'}, {lname: 'lname3', fname: 'fname3'}] | null
> (1 rows)
> cqlsh:t360> UPDATE users USING TIMESTAMP 1458019725701 SET names = [{ fname: 'fname1', lname: 'lname1'},{ fname: 'fname2', lname: 'lname2'},{ fname: 'fname3', lname: 'lname3'}] WHERE id='a';

> (1 rows)
> {code}
> => the list doesn't get replaced, it gets appended, which is not the expected/desired result
