First run options shouldn't appear if no choice

[njw]

When running a fresh flash of shr-lite, I was prompted for my preferred language, and profile. However, in each case there was only one option (us-english and illume-shr). There was therefore no need to ask either of there questions.

Any first-run questions should not appear if there is only one choice (it should be silently chosen).

That's an upstream "issue", the first part of the first run wizard is done my e17 and we don't control it, you should probably suggest that to them.

Although I think it's a good idea to keep them, as it's a minor inconvenience to some, and may be useful to others.

My reply from the ML on why this is a bad idea:
Lets say you write a manual for SHR about first time wizard atm it'll say something like: "Step one, choose your preferred language", if we'll only show this screen when there are at least two languages, the manual will have to say: "Step one, choose your preferred language, if you don't see a screen for choosing the language this probably means you only have one language in your image, don't worry, it's not an error" or something annoying like this, this is just BAD behavior.
