test: refactor fs-watch tests due to macOS issue
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.
