Can't pass API key for user scripts

[amr-cossi]

Describe the bug

Since the migration of the config reading methods, the simplest example is broken and the api key can't be declared inside a python script any more.

Expected behavior

Take into account the AutoFocusAPI.api_key value

from autofocus import AFSample, AFConnectionActivity, AFUserAgentFragment, AFRelatedMacro, AutoFocusAPI
AutoFocusAPI.api_key='__REMOVED__'
AFSample.get("8404e06ff383275462298e830bebe9540fab2092eca5523649d74e6e596ac23d")

Current behavior

Error :

API key is not set. Library requires AutoFocusAPI.api_key to be set, or apikey"
autofocus.exceptions.ClientError: (ClientError(...), 'API key is not set. Library requires AutoFocusAPI.api_key to be set, or apikeyto be provided via configuration file.

Steps to reproduce

See code above.
