feat(store): expose userData through a new getter

[rayrutjes]

cc @ehayman

I'm wondering if we should always return an empty array in case no data is available or if we should leave this check up to the user.

[ehayman]

Good point... I think in this case, returning the empty array would be safest / simplest

Undefined is the good behaviour imo

@ehayman, I'll let @Haroenv handle the release whenever he sees fit.

I agree with that, let's stay as close as possible to the helper behaviour.

You will need to check if the returned value is undefined or not.

I’ll release next week!
