Move the js reference window.plugins.backgroundGeoLocation -> window.BackgroundGeolocation:  Cordova 5 is clobbering my clobbers statement I'm finding personally as well as reported by others.  While I was in here, I changed the remaining name-style references of BackgroundGeoLocation -> BackgroundGeolocation.  Change dependency-style to npm-style with a note and commented-out pre-Cordova style
