lok: temporary workaround: disable formula mode for online

- Start empty spreadsheet, open it with two users (let's call them A &
B).
- Type "=" with user A.
- Start moving around to different cells with user B.

=> Cell name of user B's selected cell is entered in user A's formula.

This is due to the fact that ScModel::GetInputHandler() returns always
the input handler which is handling the edited formula and not the
input handler of the current view.

That really messes up collaborative editing, so better to disable it,
until we implement an alternative solution.
