eval openHandles in node > 20.15.1

[santicordone]

When running Jest tests that include the eval command, an open handle is left, preventing Jest from exiting cleanly.

this can be easily reproduce using node 20.15.1 or higher and adding a test in the test/integration/commands/eval.js
like so:
(example form the documentation https://www.npmjs.com/package/ioredis-mock#lua-scripting )

    it('test open handle error', async () => {
      redis.set('k1', 5).then(() => {
        redis[command]('return redis.call("GET", "k1") * 10').then(result => {
          expect(result).toBe(5 * 10)
        })
      })
    })

the result when running jest --detectOpenHandles is:

jest --detectOpenHandles test/integration/commands/eval
 PASS  test/integration/commands/eval.js
 PASS  test/integration/commands/evalsha.js

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