Make test harness exit with a non-zero code when there's test failure (#4889)

Browse Source 
* Rename variables to better convey what they're about

* Refactor comments so that they make more sense

* In Node.js, call the wrapper's execute function

The function sets up callbacks necessary for
exiting the process with the appropriate exit code.
https://github.com/jasmine/jasmine-npm/blob/v3.4.0/lib/jasmine.js#L235

* No need to configure the default reporter manually

The .execute() function does it

* Add note on which path comes from which npm package

* Note that other properties of the process object are referenced too
