Subject: [PATCH] process: ignore asyncId 0 in exception handler
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Today, the global uncaught exception handler is the only
place where asyncId 0 is not ignored and we still proceed
to call emitAfter. This would've already failed one of
our correctness tests in async_hooks if not for some other
code meant to handle a different edge case.

Fixes: https://github.com/nodejs/node/issues/22982
