fix: go to previous step when connection fails (coder#77)

- happens when an error is encountered during connection (like
exceptions caused by an expired token)
- right now the auth wizard stays on the last step.
- with this changeset the auth steps reset to the initial sign in for
auto-connect, or it goes back one step back to the token input step for
manual authentication
