Code review comment for lp://qastaging/~nikwen/ubuntu-calculator-app/paste-zero-fix

Thank you for your review, Bartosz. I'll fix the brackets thing as soon as possible.

However, I'm incredibly busy at the moment and it will take at least one and a half weeks until I have time for that again.

Regarding the autopilot tests: I don't know how to fit them into my schedule at the moment. If you write some though, I'll happily review them. :)

Cheers,
Niklas
