Restore user autoregistration with email addresses (#19261)
Unfortunately #18789 disabled autoregistration using email addresses as they would
be shortcut to email address does not exist.

This PR attempts to restore autoregistration by allowing an unknown email address
to percolate through to the autoregistration path of UserSignin.

Fix #19256
