fix: allow user to see error messages when url handler fails

Applies something similar to what was recommended in #438 (though this doesn't solve that issue)

Tested:
- built binary
- ran install from binary
- ran logos from binary
- accomplished sign on
- checked desktop in ~/.local/share/applications to ensure it looked right
- simulated failure in edited script, echo displays properly.
