Cleanup custom exception kwarg handling (#602)

* Cleanup custom exceptions

* Read custom keyword arguments from kwargs
* Pass all input args to the super

Earlier behavior:
Got error: AuthenticationException((('Error logging in: 192.168.xx.xx: LOGIN_ERROR(-1501)',), <SmartErrorCode.LOGIN_ERROR: -1501>))

New behavior:
Got error: AuthenticationException('Error logging in: 192.168.xx.xx: LOGIN_ERROR(-1501)')

* Pass UnsupportedDeviceException kwargs to parent, too
