Daniel Becker 03c465dac1 IMPALA-11719: Inconsistency in printing NULL values
NULL values are printed as "NULL" if they are top level or in
collections, but as "null" in structs. We should print collections and
structs in JSON form, so it should be "null" in collections, too. Hive
also follows the latter (correct) approach.

This commit changes the printing of NULL values to "null" in
collections.

Testing:
 - Modified the tests to expect "null" instead of "NULL" in collections.
