some issues running test-suite-upload-from-sciunit.ipynb

I encountered the following issues running test-suite-upload-from-sciunit.ipynb.
(I was using dev branch for sciunit and I saw it has substantial changes compared to master, so It would be a good idea to revisit this example ones the dev branch PR is merged)

in [22] -> models[1].set_attrs({'izhikevich2007Cell':{'a':'0.04 per_ms'}})

  File "test_suit.py", line 19, in <module>
    models[1].set_attrs({'izhikevich2007Cell':{'a':'0.04 per_ms'}})
TypeError: set_attrs() takes 1 positional argument but 2 were given

workaround : remove attr

in [34] -> test2 = AnotherTest(observation={'mean':3, 'std':8, ...)

NameError: name 'AnotherTest' is not defined

So, replace AnotherTest with TestFromJupyterNotebook()

in [39] -> responses = client_instance.upload_suite_score(suite, score_matrix)

ERROR:scidash_api.mapper:CLIENT -> INVALID DATA: {'sort_key': ['required field']}

Workaround: adding keys manually.

in [39] -> responses = client_instance.upload_suite_score(suite, score_matrix)

{'errors': {'model_instance': {'run_params': ['Not a valid string.']}, 'score_class': {'url': ['Enter a valid URL.']}}, 'success': False}
