This reverts commit 29207af.
This fixes a nasty bug that occurred when a URL fragment in a Twitter user's website is present but empty (e.g. "http://example.com#"). In this case, the @normalized_fragment instance variable in an Addressable::URI object is set every time the normalized_fragment method is invoked, setting the instance variable, thus violating the object's frozen state. Closes sferik/t#197.
