Can we add a rule test for this?

[elidupuis]

@bmish Interestingly, it appears that there is a test for route templates already:

ember-template-lint/test/unit/rules/no-this-in-template-only-components-test.js

Lines 13 to 18 in 1ed2f46

	{
	template: '{{my-component model=this.model}}',
	meta: {
	filePath: 'app/templates/route-template.hbs',
	},
	},

But something is missing because this rule definitely flags this.foo usage in our route templates.
