Incorrect exception type raised

[sirdodger]

I had an error where my RSA private key was not being loaded. In api_client.py:679, I would expect an ArgumentException to be raised. However, due to the way the exception is raised, I am getting a TypeError exception pointing to api_exception.py:56 instead. (Note that there are other scenarios that raise exceptions that will similarly cause problems.)

Traceback (most recent call last):
...
