tdf#103984 : For bubble charts append data column...

for "values-size" role too, after parsing in
InternalDataProvider::createDataSequenceFromArray().
Without this, embedded bubble charts in documents(MSO) other
than spreadsheets will be empty when imported.

Also adds docx import chart2-unit-test in chart2import.cxx
