DO NOT MERGE -- test to see if wheel issue is resolved by new wheels

The failure reported in astropy/package-template#37 was thought to be because the astropy wheel was built against a different version of numpy than the numpy wheel used on travis.

The solution in astropy/package-template#44 addresses that by building astropy and scipy wheels for each version of numpy.

This PR is an easy way to see if that solution actually fixes this problem.
