Better UX while subcategories are loading

[mollyhenderson]

When you click on a category from the landing page and the subcategories list is loading, we currently display a title along the lines of "Ok! What type of would you like to find?"

We should not display the title until the list has loaded.

(Note that the most up-to-date versions of both UI & API are at the branches feature/api-2)

This is because you removed the const - please see my comment in your PR on changing the const's

Nah this is preexisting - it only happens while the subcategories are loading, so it's more apparent now that that takes longer.

Now that I'm thinking about it though, this isn't really the right fix for this - we either shouldn't display anything while loading or we should have a loading indicator. I'll update the description
