small bug: does not auto close when using keyboard shortcut to select layout

[imthenachoman]

If you click on a layout, it'll move/resize the window and then hide the kTile window.

If you use a keyboard shortcut to select a layout, it'll move/resize the window, but it does not hide the kTile window.

I've pushed a fix for this to the repo but havn't repackaged the script yet as I'm looking into a separate issue with compiling the kwin script.
