islandora#1059: HTTP error 500 on /media/:mid?_format=jsonld if Media lacks File

[xurizaemon]

GitHub Issue: #1059

What does this Pull Request do?

Prevent a (not user facing) error when a Media lacks an associated File and /media/123456?_format=jsonld is requested for the Media item.

Instead of trying to return an @id with the File URI, we return the existing @id which has come from the Media entity.

What's new?

• When no file is attached and $file is FALSE, do not overwrite the JSON @id value with the file URL
• Media will then use the Media's URL

How should this be tested?

Before patch:

1. Create a Media entity which has no File attached
2. Request /media/123456?_format=jsonld for that file
3. See error in Drupal logs

After patch:

2. Request /media/123456?_format=jsonld for that file
3. See no error in Drupal logs
