[Bug] Incorrect guid value on query.get_current_user()

[ajhoyt]

Description of Issue

From my understanding, the guid is meant to belong to whatever user signed in on yahoo oauth, however when i run [get_current_user()](https://yfpy.uberfastman.com/models/#yfpy.models.User) it has been returning the guid of the app developer that registered the app on yahoo's API. Am I doing something wrong, misreading documentation, or is this a bug?

Additional Information as Applicable

This is meant for an app where users can log in and access their various leagues to get analytics, trade/waiver suggestions, etc. But right now no matter what yahoo account goes through oauth they all are treated as the app developer (who has a team in the league) rather than themselves
