TableView: Do not select input on keydown

In the Spreadsheet app, selecting a cell and typing something (like
"1") would create an empty editing delegate, set "1" as its value and
immediately select the entire contents of the text box. If your goal
was to type "123", that "1" was selected and will be replaced by "23".

This changes the behavior of TableView to not select the editing
delegate's contents if its creation was a result of a keydown event.
