tdf#124883: don't drop data field names on import

The name attribute of dataField element was already read in
PivotTable::importDataField; and then it was ignored in
PivotTableField::convertDataField. ScDataPilotFieldObj had no
handler for name in its ScDataPilotFieldObj::[gs]etPropertyValue,
although it has [gs]etName for that - so this change puts pieces
together to allow to use the imported name correctly.
