New_api exception: 'Client'object has no attribute 'isTokenRefreshed'

[Ayuus]

After installing the 'new_api' branch (which I could not have done without this post and this post, as for some reason, library pyporscheconnectapi was not correct version), I installed the integration.
Starting the integration fails with error message: 'Client'object has no attribute 'isTokenRefreshed'
After commenting out line 209 (if IsTokenRefreshed():) in file init.py, the integration loaded and I was able to see my car's data.

Tnx @Ayuus. I can confirm that this is also working for me.

EDIT: it was working ok for couple of hours and then it stopped working.
