Feature-coupled step definitions

[nodunayo]

@tomstuart pointed out here that the project was suffering from "feature-coupled step definitions".

Let's refactor the step definitions so that we're not susceptible to this pain!

@nodunayo is it alright if I pick this up?

@flyinggrizzly I'm mid organising a pairing session with @tomstuart to complete this! I'll hang onto it for a few more weeks.

If we don't manage to do it by April, then I'll ping you to pick it up.

Thanks. :-)
