Service Worker: Remove invalid test case for Cache.put() rejection

The test case was asserting that 'get' was not a valid method for
Cache.put(). But per the fetch spec, the Request's method is
normalized during construction so 'get' becomes 'GET' and that's
valid. There's a later test case which covers this using 'HEAD', so
just remove it.
