Update Konsole runs needle, maximize Konsole in desktop_terminal
    
    The needle match seems to have changed when bug #1957858 showed
    up, but it's actually just a text rendering change in the window
    title, it's not exactly caused by the tiny window. So not marking
    as a workaround needle.
    
    Maximizing the window makes the test work faster when we hit that
    bug, as type_safely needs to be able to see the results of its
    typing.
