Revert "test_runner: run global after() hook earlier"
This reverts commit 6346bdc5.
Reason for revert: breaking CI
See https://ci.nodejs.org/job/node-test-pull-request/53201/ and https://ci.nodejs.org/job/node-test-pull-request/53200/ where test-runner-output.mjs
failed everywhere, though the changes are unrelated. This test also fails for me locally consistently unless I revert https://github.com/nodejs/node/pull/49059
