Error when trying to access cloud API

[cycomanic]

I see an error when trying to access the cloud API. It seems like the access token does not work properly. See below

[ins] In [6]: rmcl.register_device_s("evdfgryb")
Out[6]: True

[ins] In [7]: rmcl.Item.get_by_id_s('')

I received a similar response when trying to connect to the rM cloud with rmfuse:

@grwlf @lckarssen see my pull request #2 on how to fix this.

[lckarssen]

I confirm that the patch in PR #2 works. :+1:

Thanks for the quick solution @cycomanic!

[sergei-mironov]

2 works for me too
