Tests issue

First of all, thanks for this template or boilerplate, there is a lot of modules that I learnt about.

When I run `npm run test` a lot of tests are failing like below, although I am running `npm run dev` in another instance.

```
FAIL tests/integration/auth.test.js (11.239 s)
Auth routes
POST /v1/auth/register
✕ should return 201 and successfully register user if request data is ok (683 ms)
✕ should return 400 error if email is invalid (105 ms)
```
Correct me if I am wrong. I can see that this project is not actively maintained? The reason for this is that I am seeing some not supported modules like `xss-clean`

```
npx create-nodejs-express-app project-name
Need to install the following packages:
create-nodejs-express-app@1.7.0
Ok to proceed? (y)

npm warn deprecated inflight@1.0.6: This module is not supported, and leaks memory. Do not use it. Check out lru-cache if you want a good and tested way to coalesce async requests by a key value, which is much more comprehensive and powerful.
npm warn deprecated xss-clean@0.1.4: Package no longer supported. Contact Support at https://www.npmjs.com/support for more info.
npm warn deprecated glob@7.1.6: Glob versions prior to v9 are no longer supported
npm warn deprecated uuid@3.4.0: Please upgrade to version 7 or higher. Older versions may use Math.random() in certain circumstances, which is known to be problematic. See https://v8.dev/blog/math-random for details.

Reproduce the report with `npm run dev` running in one instance and `npm run test` in another, starting with `tests/integration/auth.test.js`. Read the failing output and inspect the reported dependency warnings, including `xss-clean`; done means the relevant integration tests pass and the unsupported dependency warnings are addressed or clearly explained.
