Remove monkey patch from Addressable::URI#normalized_query so that it can be compatible with Addressable 2.8.2

[ericfirth]

This fixes the error on #49

Removing the monkey patch entirely lead to the following error

Failed examples:

rspec ./spec/postrank-uri_spec.rb:76 # PostRank::URI normalize cleans whitespace in PostRank::URIs

So I split on whitespace and took the first item. I initially tried just stripping the URI as a string, but then got

     Failure/Error: expect(n('http://igvita.com/a/../? #test')).to eq(igvita)

       expected: "http://igvita.com/"
            got: "http://igvita.com/?%20"

Happy to make any changes needed.
