Legacy card should not have a fallback title

[creotutar]

Yext answers has been suppressing a title in a result card with title: null since 03/11/2020. Noticing that this suppression is no longer working with the Legacy card, and instead of an empty title, we are defaulting to entity title

example data mappings config

    promotions: {
      card: {
dataMappings: {
title: ""
}
      }
    },

Environment:
using dist/answers-umd.js
v0.13.2

@creotutar what's the use case for having an empty title?

Yext answers use case is a promotional button (and I believe another client is using this in a similar way)
