The test for issue #130 depends on content from the internet

[gromgull]

https://github.com/RDFLib/rdflib/blob/master/test/test_issue130.py tests #130, by loading a document from http://linked-data.ru/example

Unfortunately they've gone and changed the content :)

We could rewrite with a http-server setup that will do a redirect, like https://github.com/RDFLib/rdflib/blob/master/test/test_conneg.py does.
