Reporter summary failing when used with custom pool

[nazarhussain]

Describe the bug

When we use a custom pool with default reporter settings, it failed withe following error.

Error: Task instance was not found for suite "testing skipped"
 ❯ getReportedTask node_modules/.pnpm/[email protected]_@[email protected]/node_modules/vitest/dist/chunks/cli-api.Dkt_XoKq.js:11494:11
 ❯ TestCollection.[Symbol.iterator] node_modules/.pnpm/[email protected]_@[email protected]/node_modules/vitest/dist/chunks/cli-api.Dkt_XoKq.js:11359:13
 ❯ TestCollection.allTests node_modules/.pnpm/[email protected]_@[email protected]/node_modules/vitest/dist/chunks/cli-api.Dkt_XoKq.js:11305:16
 ❯ SummaryReporter.onTestModuleCollected node_modules/.pnpm/[email protected]_@[email protected]/node_modules/vitest/dist/chunks/index.C1f-_gvH.js:1215:25
 ❯ DefaultReporter.onTestModuleCollected node_modules/.pnpm/[email protected]_@[email protected]/node_modules/vitest/dist/chunks/index.C1f-_gvH.js:1429:19
 ❯ node_modules/.pnpm/[email protected]_@[email protected]/node_modules/vitest/dist/chunks/cli-api.Dkt_XoKq.js:13221:58

And this happens for any root level test suite.

Reproduction

Can be tried on the following repo.

https://github.com/nazarhussain/vitest-in-process-pool/tree/nh/vitest-3-support

If following reporter settings are added, then the error is resolved.

    reporters: [["default", {"summary": false}]]

Additionally following patch can also fix the problem.
