Reproduction of 3.13.0 infinite loop in #659

[patocallaghan]

This reproduces the infinite loop issue I opened in #659

I've added two types of component:

1. my-component - js + template, Infinite loop is triggered from the template
2. another-component - js only. Infinite loop is triggered from the init hook

yarn ember test --server --filter="Integration | Component | my-component: it renders"

yarn ember test --server --filter="Unit | Component | another-component: it creates correctly"

Also worth noting while there is PR to make ember-cp-validations compatible with 3.13 in #653 I find this issue is still happening in spite of cherry-picking that fix. So I opted to keep this PR smaller by only bumping to ember-source 3.13.0-beta.5

Edit: I've also added a reproduction of this happening in a running app (see #659 (comment)). You can see the effects by running yarn start and visiting http:localhost:4200.
