        Tests for smartdelete should only occur after double-click
        https://bugs.webkit.org/show_bug.cgi?id=35314

        Fixes the tests to make selections using the mouse in order
        to force smart-delete. It also adds/modifies tests to have them correctly
        identify cases where we are smart-deleting, but shouldn't be.

        Fixing to smart-delete only on mouse-based selections will be a followup patch.
