worker: remove messageerror listeners on exit

[dayun6530]

Fixes a typo in the worker exit cleanup so messageerror listeners are removed before the exit event is emitted.

Adds a regression test covering the listener cleanup behavior.

Tests:

• python3 tools/test.py --mode=release parallel/test-worker-messageerror-listener-cleanup
• make lint-js

Fixes: #65782

Hi @nodejs/workers, just following up on this PR.
It fixes #65782 by removing messageerror listeners on worker exit and adds a regression test for the cleanup behavior.
The targeted test and make lint-js pass locally.
When someone has a chance, could you please take a look and start CI if appropriate? Thanks!
