Missing snapshot summary

[SimenB]

Made debugging jestjs/jest#8665 confusing as we only saw the exit status but no errors. Temporarily using the default reporter had this output:

Solved by #23 I believe?

This seems be causing a lot of problems for people with jestjs/jest#9324. It might be good to make showPaths default to true.

Also, I don't think #23 universally solves it. I observed an issue where Jest exited with status code 1 because a snapshot was obsolete, but it wasn't related to the file I was running the test for:

 PASS   lint  packages/darwin/src/components/AcessibilityText/index.js
  ✓ ESLint (843 ms)

Snapshot Summary
 › 5 snapshot files obsolete from 5 test suites. To remove them all, re-run jest with `-u`.
   ↳   • servers/tvui-nodequark/src/routes/videos/stubsFocusedTall/__functional__/__snapshots__/route.js.snap

Therefore, when I did console.log(testResult); in onTestResult, I didn't see anything about this snapshot, which is not surprising, because it's for a different file.

I'm not sure what Jest API should be used to figure out if unrelated snapshots are going to cause a non-0 status code exit.
