test: fix dangling promise in test_runner no isolation test setup

[JakobJingleheimer]

The --imported / --required file contained an un-awaited dynamic import, so it's subsequent code was not guaranteed to finish before the entry-point starts. Strangely that should have caused this test to fail some times, but it seems to be consistently fast enough so that the race condition doesn't occur.

I checked with the original author of the test, and this was not intended (it was only done that way in an attempt to simplify setup and recycle fixtures).

However, after speed improvements in #57419, the race condition was exposed and does occur consistently (causing the global hooks to get registered out of their intended/expected sequence).

The test is passing on the --import case but failing for the --require case (red lines are missing in actual vs expected):

before(): global
before one: <root>
suite one
before two: <root>
suite two
- beforeEach(): global
beforeEach one: suite one - test
beforeEach two: suite one - test
suite one - test
- afterEach(): global
afterEach one: suite one - test
afterEach two: suite one - test
before suite two: suite two
- beforeEach(): global
beforeEach one: suite two - test
beforeEach two: suite two - test
suite two - test
- afterEach(): global
afterEach one: suite two - test
afterEach two: suite two - test
- after(): global
after one: <root>
after two: <root>

@avivkeller and I did some digging, and they've summarised our findings over here (but let's keep the discussion of it to this PR) #57419 (comment).

can we add tests for both require and import in cjs?

[JakobJingleheimer]

There is already in this PR, no?

[MoLow]

I might be missing it but where is there a cjs test with import?

[JakobJingleheimer]

OH, sorry I think I misunderstood. You want

node --import  global.cjs test.js
node --require global.cjs test.js // this exists
node --import  global.mjs test.js // this exists

[JakobJingleheimer]

Done (and the import CJS case passes): 6a38d32
