grunt clean doesn't work

[rsippl]

"grunt clean" is supposed to clean the www directory, but it doesn't (although it seems to do quite a lot).

Adding this line at the end of Gruntfile.js fixes it for me:

grunt.loadNpmTasks('grunt-contrib-clean');

IIUC, this should be added to templates/common/_Gruntfile.js.

This issue causes some trouble. For example, "grunt serve:compress" uses the production environment (which is fine) but a subsequent "grunt serve" doesn't switch back to development.

Looks like cordova-cli 5.2 add a clean command which is loaded after the grunt-contrib-clean task.

It's kind of hacky but during the 'Register tasks for all Cordova commands' I just leave out the clean command
