tdf#125754 sw_redlinehide: avoid recursive layout in SetHideRedlines()

During SwLayHelper::CheckInsertPage(), SwRootFrame::CheckViewLayout() is
called, which may change the size of the view, which causes a
StartAction()/EndAction(), therefore layouting the frames existing at
that point, which moves some content onto the newly created frame, but
CheckInsertPage() expects to find only SwLayoutFrames on it and crashes.

To avoid that, do StartAction()/EndAction() in the UI caller of
SwRootFrame::SetHideRedlines() already; the other callers in
Undo/DocumentRedlineManager should already be covered by Actions.
