sw: fix AppendRedline() creating empty redlines for Outside

This happens on tdf#133967 bugdoc with the Delete/Delete case first, in
line 1445 - the start positions are equal, so the new redline is empty
=> DocumentRedlineManager.cxx:92: redline table corrupted: empty redline

Similar bugs exist for Delete/Insert case in line 1725 and Format/? case
in line 1892, the latter even checks a nonsensical condition
*pEnd != *pRStt that is always true for Outside case.

It's like that since inital CVS import.
