Checks if synonym val exists before access

[matentzn]

The current obographs serialiser creates

{
      "id" : "http://purl.obolibrary.org/obo/OBA_2050220",
      "lbl" : "vascular cell adhesion protein 1 amount",
      "type" : "CLASS",
      "meta" : {
        "definition" : {
          "val" : "The amount of a vascular cell adhesion protein 1 when measured in anatomical entity.",
          "xrefs" : [ "AUTO:patterns/patterns/entity_attribute_location" ]
        },
        "synonyms" : [ {
          "pred" : "hasExactSynonym"
        }]
      }
    }

So we need to check if the value exists before accessing it to not fail hard.

This is not tested.

Of course we should use the pydantic from the linkml

.get

Suggested change

	synonyms = [s["val"] for s in meta["synonyms"] if "val" in s]
	synonyms = [s.get("val") for s in meta.get("synonyms", []) if s.get("val")]

like this?
