Disable EmberCLI JS minification

When precompiling assets in production, we ensure that we are not
minifying the JavaScript assets twice.

Duplicating minification can slow down assets precompilation
considerably.

Closes [tricknotes/ember-cli-rails#124][124] and
[tricknotes/ember-cli-rails#123][123].
