Chat with not yet keybase user via email handle has UX problem

When I discovered that keybase allowed me to start a chat with someone not on keybase just via their email, I thought it was brilliant idea! Unfortunately it turns out process of onboarding that new user is not very smooth which leaves new user with a feeling of it being broken. Below I'll try to describe how it went in my case to outline the problem:

- I decided to get some conspirators onto keybase, to form a team and go about conspiring.
- I start a new chat and add all of their emails. New chat even offered me to create a team!

- **problem** is however that after I entered a team name and clicked "created team" button it created a new team **unrelated** team. Chat thread does not appear under the team and I still see that prompt to create a team.

- I also had another convenient message suggesting me how to summon my conspirators

- I did provided them with a link, they installed an app, created an account with the emails I have had there, but **were not able to see the chat**.


- So we kept on wondering why we were able to chat in keybase still without my conspirator being able to see the chats I've started via email


- In the end we have figured out that reason why conspirator was unable to see those chats is because "email address had to be made searchable"

-----------

I think onboarding by just starting a chat with someones email can make a huge difference if the process is smooth, but if it's full of pitfalls like in our experience it can have backfire effect.

Start by reproducing the email-handle chat onboarding flow described in the issue, including team creation and making an email address searchable. Compare what the inviter and newly registered participant see in the attached screenshots; done means the created team is associated with the chat and invited users can find and open it without discovering a hidden searchability requirement.
