    tdf#157596: add partly-deleted paragraphs to hidden list during fileopen
    
    - regression from commit 2413f213625253a9c2b1787b3b9fe859d724a9bd
    - if a paragraph is partly deleted, add it to the "hidden" list.
    - if we delete -at least- a single character from a paragraph (during 
Record Track Changes is enabled), Writer thinks the whole paragraph and the 
numbering is deleted. Therefore, the numbering of the paragraph does not get 
added to the hidden list.
    - this patch adds the partly-deleted paragraph numbering to the hidden list 
during fileopen.
    - added a unit test
