    Exception.message deprecated in py26 (bug 1070890)

    In the case of IntegrityError (e), e is wrapping a DBAPIError[1] with more
    information about the context of the exception -- context that we do NOT
    want to expose to our own API users (however, that context should still
    be logged). In the case of an integrity error, str(e.orig) will produce
    exactly what we're producing with e.message today: a user-friendly
    message such as 'column name is not unique'

    This change should not impact what is logged or returned to the API
    user -- just eliminate the deprecation warning.
