DOC: remove empty attribute/method lists from class docstrings html page
Follow-up on https://github.com/pandas-dev/pandas/pull/18202 (RangeIndex was forgotten)

This is not really ideal, as we then get warnings about None not being a method. Maybe we could somehow connect with the numpydoc process and after its processing remove it ..

So that is what I did. Not fully sure this is a good idea, as it adds to the technical debt of our complex doc building machinery, but, it solves the warnings and ugly html output (see eg methods section in http://pandas-docs.github.io/pandas-docs-travis/generated/pandas.Int64Index.html#pandas.Int64Index) # [Codecov](https://codecov.io/gh/pandas-dev/pandas/pull/19949?src=pr&el=h1) Report

 I think since you're using an official sphinx event to processes the docstring, it's fine. Much less of a hack than what we've done in the past :) Travis log file looks good now!
