Visiting http://localhost:9099/work/3fb95f66-3083-44cb-b64d-0f3c84024443 throws this error:

```
Unhandled rejection TypeError: Cannot destructure property `identifiers` of 'undefined' or 'null'.
at getISBNOfEdition (/Users/Lenore/Work/Brainz/BookBrainz/bookbrainz-site/lib/client/helpers/entity.js:290:34)
at EditionTableRow (/Users/Lenore/Work/Brainz/BookBrainz/bookbrainz-site/lib/client/components/pages/entities/edition-table.js:62:15)
```

In getISBNOfEdition, entity.identifierSet.identifiers can apparently be null, which throws an error.
A check on the existence of entity.identifierSet.identifiers should be enough, but the entries should be fixed in the database
