tdf#138479 tdf#137769 sw ChangesInMargin: fix Undo in paragraphs

Fix Undo of embedded tracked deletions in paragraphs, for example
Undo of deletions Lorem->Loem->Lm resulted only Loem, moreover
a crash in the case of typing (not tracked) text before the
tracked deletions.

Now the last tracked deletion is chosen by the biggest
SwRangeRedline ID during Undo instead of the lost/modified
redline range in case of hidden redlines of the ChangesInMargin
mode.

Note: revert commit 4ad0459494303745b377c848c681a747f294fc64
(tdf#138135: sw ChangesInMargin: join characters at backspac) to
avoid crash on extra Undo (tdf#137769). Showing deleted
character sequence in margin needs grouping of hidden redlines,
as for managing tracked changes.
