Congress: fix for #463

This is a fix for https://github.com/duckduckgo/zeroclickinfo-spice/issues/463 The NY Times API doesn't seem to let you get all of the House members in one GET request so I switched the IA to work with the govtrack.us.  It shows the correct person and state now.  Unfortunately,  it doesn't have any details on voting record so I had to drop that.
