tdf#88697: sw: make WW8 export of CITATION fields compatible with

... older versions of Word and LO.

Based on a prototype patch by Yury <yury.tarasievich@gmail.com>

The problem is that Word 2003 does not understand the new CITATION field
added in commit 06f7d1a96eef5aa69d4872ff6d96eb5085296d09.

Word 2010 does appear to at least recognize it as a field.

Also fix the textual field type, which was omitted for CITATION fields,
except when the document was imported from DOCX.

(cherry picked from commit f56289ac6d7f3da7fd45dd431ce4c540aadcad56)
