Mårten Nordheim 58b37f5908 QNI manual test: Remove unnecessary capturing and wrapping
No need to capture anything by reference, it's a leftover from when
the MainWindow was changed from inside the lambda.

And no need to wrap the argument to QLatin1String.arg() with QStringView
explicitly. This change is made just for brevity and consistency.
