Hide hero button if no text for label entered

I've done a few tests with this, such as entering a load of spaces in the admin area, and they get trimmed on saving and it gets reduced back to null 😄

Interesting, I usually use null, but you've used nil? What's the difference?

I believe I'd ran into an issue where I had set a link, and then unset it, which still had the property initialized, but it was just an empty string.

I believe I've also tried the blank liquid literal, but for some reason that also wasnt working as expected, so comparing against nil did what I needed to.

Heres a link to an issue I found while trying to solve this a few weeks ago Shopify/liquid#223 and theres a better explaination here Shopify/liquid#89
