htmlsafe imports and links

[asizer]

htmlSafe is found in the @ember/string module, not the @ember/component module. Additionally, the link to the htmlSafe method was broken.

import { htmlSafe } from '@ember/string'; is deprecated as of ember-cli/ember-rfc176-data#38.

ugh, ok, but the current import { htmlSafe } from '@ember/component' doesn't exist and breaks the build at 2.16.2. Additionally, the htmlSafe link is broken in the docs right now, but the class does exist under the @ember/string module, so seems helpful to have a link to somewhere.

Took out the deprecated import statements and changed htmlSafe reference to Ember.String.htmlSafe, as the current import statement doesn't work.

Thanks for your contribution :)
