Remove the es6-promise polyfill.

Amber requires a native Promise and no longer ships or scaffolds the
polyfill; the AMD path this package declared for it was what put
amber/es6-promise back into every config.js generated around it. The
deploy, devel and test-runner bundles now require the app directly,
and the devDependency goes with it.
