After creating an account via magic link, email address must be confirmed before another magic link can be used

[sevenseacat]

ie.

• Register new account via magic link
• Click magic link in email
• I am now signed in
• I get an email confirmation email (!)
• I sign out
• I try to sign in with another magic link
• I can't, because my account is unconfirmed. (!)

This feels like a bit of an edge case but something I just noticed.

If we're creating an account via a magic link, should that count as confirmation? So we don't have to send another confirmation, and can auto-confirm the user.
