Getting token for dev fails

[appukuttan-shailesh]

testLibrary = TestLibrary(username=HBP_USERNAME, environment="dev")
currently fails as
https://validation-dev.brainsimulation.eu/auth gives Internal Server Error
and
https://validation-dev.brainsimulation.eu/login gives Invalid parameter: redirect_uri
The above are requried for authentication workflow. See here.

Current workaround:
Get token via Production and then use in Dev.
