sd lok draw text: make sure watching views have no cursors

These additional views are only created to follow the updates done in
the editing view, not to contribute additional cursors.

With this, if the first view edits a shape text and the second view is
created, then no unwanted text view cursor is created in the first view
for the shape text from the second view.

Be precise in the unit test and make sure that cursors from all views
are hidden, because even without a fix the cursor of view #2 is hidden,
but not from view #3, so the test wouldn't fail without the fix. (But
hardcoding the 0-1 and 2-3 view IDs exposed by Impress before/after
initializeForRendering() would be ugly.)
