I realised that it was blocking elsewhere. But it would be save a trip if I could supply the user public key if it was known to prevent this from becoming blocking.

I've added `NostrConnect::set_user_public_key` at commit ce05916f4acef2351e6ab648e4e7296a6d10f8d9
thanks. I've suggested so `bootstrap` shouldn't fail after `set_user_public_key` is called.
