Use babel experimental parser

Suggestion taken from:

[The issue we're encountering with this upgrade]:
emberjs/babel-plugin-ember-template-compilation#101

[Suggested workaround from the discussed issue]:
https://github.com/simonihmig/responsive-image/pull/1292/files

[Is it OK to use?]:
ember-cli/ember-app-blueprint#44 (comment)

I image the experimental parser will be become the primary at some point
and importing from experimental will result in an error.
