Title: Recommend in-place building instead "setup.py develop" for testing

Issue #424 was fundamentally caused by using `python setup.py develop`. There was a `.pth` file with a path pointing back to the git repo, so when trying to import astropy it was always picking up files in my git repo source directory instead of the installed version.

This PR updates the testing guidelines to recommend using `python setup.py build_ext --inplace` instead of `develop`.
