tdf#101464 fix SwAccessibleMap::mpEvents assertions switching PrintPreview

The problem here is that when switching to the print preview, there are
2 view shells, SwEditShell::UpdateTable() is called and the first one
does some layouting in ImplEndAction(); this creates a11y events for the
2nd print preview one (see loops in SwViewShellImp::Invalidate*) and
stores them in the SwAccessibleMap since there is an Action going on;
then SwViewShell::ImplEndAction() for the print preview shell is called
but it returns early without sending out the events, so they remain
until the ~SwAccessibleMap asserts about them.
