When generating definitions/syns, and multiple labels are present, dosdp tools create weird values.

When the source ontology, say foodon, contains terms with more than one label (shrimp, "shrimp as a food source"), dosdp tools generate bad looking definitions:

```
An exposure to shrimp as food sourceshrimp via ingestion.
```

and synonyms:

```
shrimp as food sourceshrimp exposure via ingestion
```
