onBoarding: When an invitation link is opened by Bob - Bob should agree for writing into his address book.

[silkroadnomad]

Bob is scanning a link with an onboarding token, when clicked on Bobs side will automatically send Aice data into Bobs address book. The situation is: Bob doesn't know that Alice writes her contact data into his address book.

We need a confirmation step here.

When ever we connect to Alice, Alice already gave permission to give the contact data to Bob when generating the QR code.

She is requesting Bob's data automatically, which opens (after successful connection) the confirmation popup (Address Request) on Bob's side. Bob confirms to send his address
(and requests in return Alice contact data is not necessary anymore) See #38
