Fixed a case where old data was not deleted correctly from the store when
inserting new values. This was causing tracker-extract to log errors for
multi-disc music albums stored as FLAC files with embedded CUE sheets.
Improved .odt extraction, fixing issues with hyphenated words.
OpenBSD: Fixed build (thanks to Antoine Jacoutot)
functional-tests: Fixed a cause of intermittent failures,
removed some unused data files.
