Remove usage of deprecated .message attribute of exceptions.
This fixes
https://bugs.launchpad.net/ipython/+bug/407836.
The .message attribute of Exception is being deprecated in Python 2.6.
All new code should simply use args[0] for this purpose. There are still
a few places that modules in external use this. Hopefully these will
be updated soon.
