A timer wrapper such as a browser extension, policy, or automation harness can block a call and return null instead of a handle. patchTimer then read `.refresh` on that null value and threw synchronously.
Treat a nullish handle as non-refreshable so the patched timer keeps working.

`clearTimeout` is patched by `zone.js`, and it finally calls the native delegate of `clearTimeout`,
the current implemention only call `clearNative(id)`, but it should call on object `global` like
`clearNative.call(global, id)`. Otherwise in some env, it will throw error
`clearTimeout called on an object that does not implement interface Window`
