  succeeds use `yarn`, if it fails use `npm`.

- Use “Chrome” instead of "Google Chrome", It  will try to use current active browser.
  otherwise, use default.

Re: #1174

* Don't strip stack traces of evaluated webpack code

* Strip stack traces at the end of a string

because the last line doesn't always have a `\n` and `create-react-app` is leaving the last line of the stack traces present in the error messages

In my tests, jsdom was throwing a "SecurityError" at HistoryImpl._sharedPushAndReplaceState (node_modules/react-scripts/node_modules/jsdom/lib/jsdom/living/window/History-impl.js:87:15)

This happens because document.URL defaults to "about:blank". Unfortunately, if you interact with the History object it tries and fails to parse the URL, causing a "SecurityError" to be thrown. Setting the default URL to "http://localhost" fixes this issue.

Jest matches moduleNameMapper regexes with module names, not the full
file path, so the negative lookahead doesn’t work for filtering out
JS files, because they can be imported without the extension. So paths
like `lodash.assign` and `../utils/range` were mislabeled as resources
with unknown file extensions because they have a dot in the name.

As a stopgap measure, revert the moduleNameMapper regex added in #1077.
