tdf#71409: always create edit engine instance for the input window.

In order to properly manage accessibility events esp when no letters
are typed.  Without this, doing things like:

1) hit F2 to active cell edit,
2) hit ESC to deactivate,
3) go back to 1) and repeat the cycle several times,
4) hit Shift-Ctrl-F2 to activate the top input window

would result in duplicated accessibility events fired, the number of
which depends on how many times the above step was repeated.
