useSendPasswordResetEmail requires the user to be logged in

[AndreasHaaversen]

The typical use-case for this hook is to implement "forgotten password"-type functionality. That isn't possible with the hook as is since it requires the user to log in first.

The Firebase SDK itself doesn't require a user to be logged in. I don't think we should wrap the SDK in more restrictions than it already provides.

@AndreasHaaversen good spot, this was an oversight on my side. I'll get this resolved and a patch release out shortly.
