-----------------------------------
Description:
isNewSchema() method checks if top-level schema or any of the deeper map
schemas has changed. The last one doesn't work properly.
"deeperSchemaChanged" equals true even when two map strings have the same
children fields.
Discovered while trying to fix [DRILL-2385|DRILL-2385].
Dataset for reproducing (MAP<REQUIRED> datatype object):
{"oooi":{"oa":{"oab":{"oabc":1}}}}
