Pre-computed signatures from tool_consumer_spec were invalid

They have been regenerated from http://oauth.googlecode.com/svn/code/javascript/example/signature.html and now make the tests pass correctly
Outcome spec was failing tests because of a mallformed xml

The precomputed xml used to validate specs were wrongly not closing
itself as : <imsx_description/>

According to xml specification: http://www.w3.org/TR/REC-xml/ elements
with empty content should close itself in the same tag.

will likely reject the submission since it would mean that there is
nothing to submit.
