In `macOS`, fsevents generated immediately before start watching may leak into the event callback. See: https://github.com/nodejs/node/issues/54450 for an explanation. This might be fixed at some point in `libuv` though it may take some time (see: https://github.com/libuv/libuv/issues/3866). This commit comes in anticipation of the soon-to-be-released `libuv@1.49.0` which was making these tests very flaky.
