Adjust the default browsers to be a single list and remove it from the build output; it only affects CSS now

* Revert Lerna dependency, there's too many bugs in v3

* Remove `mjs` support

This reverts commit b43ad04b.

This reverts commit 2c34d5b6.

To analyze Webpack bundles, a "stats" JSON is required.

This PR allows that file to be created and saved to the `build`
directory, so that users can use it with Webpack-specific insight
tools like `webpack-bundle-analyzer` without ejecting their
application.

Updated the README to include details for how to do this.

Support for .mjs files added in #3239 did not account for npm libraries which ship native mjs files alongside js files. This accounts for this by ensuring .js files resolve before their accompanying .mjs file. Note that this is not an ideal end state since selecting a .mjs over a .js extension should be the result of whether `import` was used instead of `require()` in a node environment with native ESM support (currently via `--experimental-modules`). Instead, this change just *always* selects a .js extension before the .mjs extension if it exists.

This unbreaks support for using GraphQL (relay, apollo, etc) within create-react-app projects.

Note: monorepos won't work after eject.
Can be fixed easily with JEST 22.0.?+ which has file pattern matches against realpaths.

* Filter tests to run only tests in monorepo components included by the app.
(Not sure this is desireable, might be cool to be able to easily run all tests in monorepo from one app.)

* Fix conditions for when to use template.

* Fix eject.

* Remove code that is not needed w/ Jest 22.

* Include all cra-comp tests in monorepo instead of trying to include only tests that are dependencies of app.
(tests can be easily filtered via jest cli if desired, e.g. 'npm test -- myapp comp1')

* Enhance Jest config error for `setupTestFrameworkScriptFile`

I wasn't aware of the fact that users of c-r-a could just define
`src/setupTests.js` and it would be configured with Jest - I nearly
ejected before I found a GitHub issue that confirmed this functionality.

I thought it might be a nice idea to add it to the error about Jest
config overrides to stop others ejecting when they don't need to.
