Fixed patch [^CASSANDRA-12594-3.0_2.txt] which uses current server version
protocol version instead of hardcoding to 4.

> {noformat}
> This is because the code doesn't consider that the cell may be a frozen
> collection, and attempts to get the string representation using the value
> type which doesn't work.
> Example data:
> {noformat}
> CREATE KEYSPACE simple WITH replication = {'class': 'SimpleStrategy',
> 'replication_factor': '1'};
> CREATE TABLE simple.unfrozen_map (
> k int PRIMARY KEY,
> m map<text, frozen<tuple<text, text>>>
> );
> CREATE TABLE simple.frozen_map (
> k int PRIMARY KEY,
> m frozen<map<text, frozen<tuple<text, text>>>>
> );
> insert into unfrozen_map (k, m) values (0, {'a': ('b', 'c'), 'd': ('e', 'f'),
> 'g': ('h', 'i')});
> insert into frozen_map (k, m) values (0, {'a': ('b', 'c'), 'd': ('e', 'f'),
> 'g': ('h', 'i')});
> {noformat}
> unfrozen_map will properly dump each cell individually, but frozen_map fails.
