Code review comment for lp://qastaging/~fboucault/ubuntu-calculator-app/startup_time

I would also explain that by removing string:
  title: i18n.tr("Calculator")
all translations will be gone after merge it to trunk.

As a result after reintroducing i18n.tr("Calculator"), all translators will need to translate i18n.tr("Calculator") once again, which is time consuming and unnecessary work.

According to Convergance the same application should work with the best UX on all different platforms. Not displaying name of application in Title Bar on Desktop, is in my opinion bad UX.
