Update Heat CLI test to pass with random hash

The failing test assumes ordering of the returned JSON
blob and asserts that the given server resource precedes
another resource.  This updates it and allows the test
to pass when the resource is listed at the end of the
section, which may happen depending on hash + dict
ordering.
