react-scripts test --onlyChanged always runs ALL tests instead of only the changed tests, yarn jest --onlyChanged works as expected.

Created by: LaurensBosscher

Describe the bug

If I run yarn jest -o, jest attempts to run 18 tests (out of the 158 in total).

If I run yarn react-scripts test -o, jest attempts to run all tests.

If I edit /node_modules/react-scripts/scripts/test.js so that only the following options are passed to Jest: "argv [ '-o' ]" Jest will still attempt to run all the tests so this doesn't seem like a configuration issue.

Did you try recovering your dependencies?

Yes, 1.16.0

Which terms did you search for in User Guide?

Jest, --watch, --onlyChanged, -o
