Run tests on ember beta, release, canary

 * Fix failing tests when using ember with glimmer2.
 * Access DOM helper using a method that is safe for both pre-glimmer2 and
glimmer2.
 * Wrap the renderedMobiledoc documentFragment in a wrapper div
   (necessary for glimmer2 teardown, see
   glimmerjs/glimmer-vm#331 and
   yapplabs/ember-wormhole#66 (comment))
 * Fixes #18.
 * Update travis node version.
 * Update package keywords and description.
