Fix auth commands requiring project root and silent ralph exit

Auth commands (login, logout, status, refresh) now fall back to the
current working directory when no project root is found, instead of
erroring out. This allows `mfbt auth login` to work from any directory.

Fix typer.Exit (click.exceptions.Exit) not being caught by
`except SystemExit` in the ralph command and handle_errors, which
caused silent exit with code 1 and no error message.

Bump version to 0.1.2.
