In case of an exception in XOAUTH2 code refresh (HTTP Error 400: Bad
Request), following exception occurs:
ERROR: While attempting to sync account 'xxx'
__init__() missing 3 required positional arguments: 'msg', 'hdrs', and 'fp'
Traceback:

raise type(e)(msg, exc_info()[2])
The exception 'e' is of type HTTPError, which does not have the same kind of
constructor as normal Python exceptions.
Instead, print the constructed message and just raise the existing
exception.
With that change, the same condition triggers another problem further on:
ERROR: While attempting to sync account 'xxx'
tuple index out of range
