The package option to enable the `boost_python` library changed from `python` to `without_python` in [this commit from last year](https://github.com/conan-community/conan-boost/commit/5cd89111396f8b724394167d3de803f636bc9716). The `test_package` was not updated accordingly. It still uses the old option [here](https://github.com/conan-io/conan-center-index/blob/master/recipes/boost/all/test_package/conanfile.py#L17) and [here](https://github.com/conan-io/conan-center-index/blob/master/recipes/boost/all/test_package/conanfile.py#L28). As a result, the `boost_python` portion of the test package has not been getting exercised, and it appears that it is in need of some TLC.
