Michael Kirk 60a39f93c6 Remove phone numbers from scannable QR Code
Initially they were there to offer richer error messages when the wrong
code was scanned.

However, we found that people were posting them publicly,
misunderstanding the QR codes to be a kind of personal identifier.

For one, this isn't useful because the QR codes, like safety numbers,
are unique *per* conversation. So they aren't useful in a generic sense.
And secondly this is bad because the QR code contains both parties phone
numbers.

Michael Kirk c1ade86a8b New fingerprint format
In coordination with Desktop and Android, iOS will be using all-numeric
fingerprints, aka "Safety Numbers".

Furthermore, the concept of verifying one identity and then the other
has been removed. Instead we ask users to exchange a single number, or
scan a single QR code. These credentials are built by combining the
users identities.
