Error loading json-ld content from https://schema.org

[ianco]

pyld is not correctly loading json-ld content from https://schema.org, when http://schema.org is used in the context.

There are two open PR's that fix this issue (#129 and #141).

It would be great to get one of these into a release, we're building JSON-LD credential support into Aries Cloudagent Python and this issue is restricting the content we are able to include in our credentials.
