[$100] Update migrate db to es script to store reviews and review summations under submissions

[callmekatootie]

Our db to es migration script does not store the reviews and review summations under submissions.

Check out how ES processor does it - https://github.com/topcoder-platform/submission-processor-es/blob/develop/src/services/ProcessorService.js#L44_L71

Expecting similar for the db to es migration script

Fixed.
