Open handle issue when testing configured express application

[christopher-watanabe-snkeos]

I configure my express application as laid out in the README using i18n-express 1.1.3 and the application starts without a problem.

However, when I test my application using Jest, I receive the following error:

Jest has detected the following 1 open handle potentially keeping Jest from exiting:

● FSEVENTWRAP

  23 |
  24 |   app.use(
> 25 |     i18n({
     |     ^

Looks like the constructor activates a file system watch on the translationsPath directory, which I think doesn't get closed in the scope of my tests. It looks like there's an option to allow closing the watcher with an abort signal https://nodejs.org/docs/latest-v18.x/api/fs.html#fswatchfilename-options-listener, but the option isn't set in the call to fs.watch.

In the meantime, since I know roughly where the issue originates, I can --forceExit my jest tests in the meantime.
