Add a helper function to the uninitialised formBuilder instance

[lucasnetau]

This change would hopefully stop issues being logged around 'formBuilder.actions.function is not a function TypeError' as it would give feedback that the formBuilder instance is still initialising and they need to wait.

@kevinchappell we could put a URL into the message that takes the developer to the docs around async init? What do you think?

That is a great idea. Should we make that message translatable?

@kevinchappell mi18n may not be initialised by that time, so I'm guessing I need a fallback

Ah right of course. English should be fine for this type message because i think mostly developers would see it.

I like the URL idea to better explain the problem
