python: KeyError shouldn't be raised from __getattr__

Browse Source 
On Python 3 hasattr only intercepts AttributeError exception.
On Python2, instead, hasattr intercepts all the exceptions.

This means __getattr__ shouldn't return KeyError when the attribute
doesn't exists, but it should raise AttributeError instead.
