emojify-display-emojis-in-company-tooltip should not force the use of `after-string`

I'm not crazy about the advice approach at all, but your particular one is also based on outdated information. Company's popup doesn't use display anymore, we settled on 'before-string. That's how the kind icons are able to be rendered, too.

So the end of the advice should be changed.

You can also try advicing company-fill-propertize instead (with an after advice), that should allow a much shorter definition.

What would be best to replace advice?
