This change adds support for logical assignment operators into babel-preset-react-app.
This PR is based on issue #10734
I have also updated E2E tests inside react-scripts so I can test it by running ./tasks/local-test.sh --test-suite kitchensink.
This is the only way I could test it. When I tried running all E2E tests it failed when publishing to local repository inside this test suite.
