ShellCorona: Activate launcher menu even when no global shortcut is set
activateLauncherMenu is invoked by the hard-coded "Meta" shortcut in KWin. The activation key is not configurable and therefore does not make sense to have different behaviors depending on whether a shortcut is configured for the application menu or not.
Or to say it in a easy way: I don't want to bind Meta+Shift+Alt+Space to the application menu so that Meta opens start menu. It makes no sense.
This patch fixes cases like .
In 267b6a8d introduced the activation helper alongside with this check, so it appears to be the intended behavior. But per the reasoning above, I consider this to be a review oversight.
