Bugfix / tests: Travis use LibreOffice PPA and fix import /export tests for good. (#4166)

Just final bits of test coverage for import/export of LibreOffice.  It turns out Travis by default installs an old LO that doesn't support PDF import.  To remedy that I use the LO PPA and also strict install the PDF import support.

Still to do in a future date is check LO exported contents includes expected strings, for now it just checks output length looks sane.
