Before this commit, when the user calls methods on a closed or errored fs event watcher, they could hit a crash since the FSEventWrap in C++ land may have already been destroyed with the internal pointer set to nullptr. This commit makes sure that the user cannot hit crashes like that, instead the methods calling on a closed watcher will be noops. Also explicitly documents that the watchers should not be used in `close` and `error` event handlers.
