Merge branch 'novemberborn-fail-start-script-overruling-nodemonjson' into fix/383
Tweak output of tests to see what's failing
Fixed test

Before it was running the exec method which had a bug, so the test was being tested with buggy code (we thought we were running a user defined setting of exec="foo" through .load, but it was actually exec="node"). This change ensures we're only passing through exactly the amount the user would.
Fixes #383

Ensure we look at the package last, after reading cli options and user prefs via nodemon.json
