Ladybug shows "Uncaught exception" for "identificatie-niet-uniek"

Ladybug shows "Uncaught exception" for "identificatie-niet-uniek"

The pipe PostZgwZaak returns in a creeerZaak:

{"type":"https://openzaak-zgw.denhaag.nl/ref/fouten/ValidationError/"," code":"invalid", "title":"Invalid input.", "status":400,"detail":"", "instance":"urn:uuid:e0464632-291c-4480-ac02-62ef5c24a0f6", "invalidParams":[{"name":"identificatie", "code":"identificatie-niet-uniek", "reason":"Deze identificatie bestaat al voor deze bronorganisatie"}]}

It would be nice if this mesage can be displayed as Status in Ladybug.

#249 Should help with this. Currently the identificatie-niet-uniek information is lost due to the higher level error handling "Uncaught exception" overwriting it. This feature will nest previous errors, so that information is retained
