Investigate default reporter broken output

[aaronabramov]

sometimes i see our concurrent reporter trying to print something to stdout/stderr while it's running tests and it results in broken output:

we should try to log everything that gets printed and find that piece that breaks the output

Is it packages/jest-cli/src/__tests__/test_scheduler.test.js? It outputs extra summaries when running it:

Fix:

diff --git i/packages/jest-cli/src/__tests__/test_scheduler.test.js w/packages/jest-cli/src/__tests__/test_scheduler.test.js

a saw it happening in other projects as well. i think ideally Jest should not allow any output break the reporter

We'll have to intercept process.std{out,err}.write then
