When the user deletes a review, remove all images associated with that review

[gigili]

This module is not yet developed, but once it does get developed we need to implement the functionality that will allow us to remove any images associated with a review when that review gets deleted. This might also happen when someone deletes a restaurant as well, because in that case all the reviews linked to it would be deleted as well so we need to make sure that images get deleted as well. This issue will be updated once the reviews modules gets created
