tests: update jest snapshot url (#3861)

This is not a cosmetic change because jest errors when run with
`CI=true`.

I got this error when running unit tests in gitlab:

```bash
FAIL unit tests/unit/functions/updatenotification_spec.js
  ● Test suite failed to run
    Outdated guide link: The snapshot guide link is outdated.Please update all snapshots while upgrading of Jest
    Expected: https://jestjs.io/docs/snapshot-testing
    Received: https://goo.gl/fbAQLP
      at validateSnapshotHeader (node_modules/@jest/snapshot-utils/build/index.js:104:12)
      at getSnapshotData (node_modules/@jest/snapshot-utils/build/index.js:156:28)
```

If you run the test without `CI=true` jest will update the file.
