tdf#142700 DOCX: fix lost track changes of images
anchored to characters or paragraphs.
Tracked deletions and insertions weren't imported,
if they contain only images anchored to character,
resulting loss of the document content: i.e. deleted
images were reappeared, as not deleted images.
Note: because change tracking of the OpenDocument
and Writer supports only text range based changes,
the fix is a workaround using zero width spaces
to create an invisible text around the anchoring point
of the images. This workaround is not used, if it's not
necessary, i.e. if the image is part of a bigger
deletion or insertion, which contains also text, not
only an image.
