tdf144058 sw track changes: fix table deletion at paragraph join

Tracked paragraph join by table deletion left empty
table in the text after accepting the changes, caused
by the non-continuous redline range over the table,
related to the copying of the formatting of the first
paragraph to the (wholly or partially) removed paragraphs.
Fixed by skipping paragraph format copying in the case
of table paragraphs.

Note: this is not enough for tables with inner redlines,
where tracked paragraph join with deletion of such a table
still leaves an empty table at the place of the table
(a problem inherited from OOo).

Regression from commit 1bbbe57dfc0b43d6b5444798d77dcdf5e4e76e49
"tdf#119571 change tracking: show layout changes at paragraph join".
