base.Resource not define __ne__() built-in function

Class base.Resource defines __eq__() built-in function, but does
not define __ne__() built-in function, so self.assertEqual works
but self.assertNotEqual does not work at all in this test case in
python2. This patch fixes it by defining __eq__() built-in function
of class base.Resource. Also fixes spelling errors:resoruces.
