Models being created without having names

[appukuttan-shailesh]

This is in context to one of our pytest checks:
test_models.py -> #4.2) Missing mandatory parameter

On the web apps, model name is a mandatory field. But the APIs seem to allow models to be created without names. E.g.:
https://model-catalog.brainsimulation.eu/#model_id.400e4aa1-bb9e-4615-ba16-dc71c44b7c2f

This causes the test to fail.

Note: it is presently unclear which fields are mandatory for models and tests. This has varied quite a bit over time, and so even I am a bit clueless. I mostly resort to trial and error when trying to identify mandatory fields... not ideal!
