ofz#3301 sw: DeleteAndJoin found yet another way to delete new redline
Not only can that happen in CompressRedlines(), it can also happen
in the SwComparePosition::Outside case when the DeleteRedline()
decides in particular circumstances to split up the inserted
new redline.
Arguably it's wrong to split up the new redline in this case;
not sure if that ever happens in a legitimate use case though.
Avoid this by removing the hack to temporarily insert the new redline
and instead create a temporary SwUnoCursor that will be corrected
on behalf of the new redline, while the new redline is parked on a
safe node.
This not only avoids the crash on this file but also makes the
"corrupted redline table" assertions go away.
