lok: sw: change tracking: deleted characters aren't deleted right away

Problem:
Start/open a document in CS Writer, and enable track changes.

- Type a few characters.
- Delete a couple of them with backspace or delete.

=> The deleted characters are still shown in the document (but not in
the tracking comment).

Findings:
In SwViewShell::ImplEndAction pRegion is 0, so no call to
SwRootFrame::Paint->vcl::Window::Invalidate occurs.
That is due to the fact that the call to SwLayAction::Action() does
not lead to populating *pRegion with rectangles
(SwViewShellImp::AddPaintRect).
In fact we stop at SwLayAction::TurboAction_ since pCnt->IsValid()
returns true and so SwLayAction::PaintContent() is never invoked.
SwFrame::IsValid() returns: mbValidPos && mbValidSize &&
mbValidPrtArea.
Here SwFrame::mbValidSize is the one that makes the difference: it is
true in Online and false in Desktop. (In our case the other 2 data
members are always true).
The reason is that the computation of the text range
(SwShellCursor::FillRects) in SwRedlineTable::LOKRedlineNotification,
which occurs just before collecting paint rectangles, leads to invoke
SwContentFrame::MakeAll which in turns set SwFrame::mbValidSize to
true.

Solution:
Call SwFrame::InvalidateSize() on any frame on which MakeAll is
invoked soon after we finish to compute the text range in
SwRedlineTable::LOKRedlineNotification.
