Studio distribution items don't have filenames

[Dinika]

Distribution items in studios sometimes dont have a label or filename. For example, for this table in studios, the resource with @id = ""https://bbp.epfl.ch/neurosciencegraph/data/reconstructedcell/24de2dd7-53c3-48c1-bf24-cf2eaf3abf5f"" has the following distributions. Note the lack of name in the first object. In the second object there is no extension. Almost all resources in this table have a similar problem:

Ideally the backend should send us the correct extension based on encoding format so in the frontend we don't rely on the filename.
