BOADICEA export is broken in some cases

Description

In some cases death and birth dates were set to be empty objects (as opposed to not set at all or set to a meaningful value), which was not handled well by the exporter

To reproduce:
1) make a node "deceased"
2) set death date
3) make it alive
4) try to export as BOADICEA
