Test for swapped out image loss during Writer export

Related to the bug fdo#52226. The fix in *.rtf and *.docx
export was this commit:
9dd5caac62083f7162d83319284df68ee83e3777
The problem was that the images were somehow swapped out but
were not swapped in during export.
Test the main Writer formats: ODT, RTF, DOC, DOCX.
