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.
