Switch to ember input helper

[RobbieTheWagner]

Just kidding, this doesn't fix the issue, but it is a step in the right direction.

We probably want to follow something like https://ember-twiddle.com/ac4ea1deedfcb7cb2b13a40c3f166932?openFiles=templates.application.hbs%2C

Might be worthwhile nailing down the failing test case, so we know it's solved.

@knownasilya this doesn't have a failing test case, just switched to the input helper, which seems to work fine. This is not part of the refactor we discussed yet.

Give https://github.com/knownasilya/ember-toggle/tree/simplify a try.

Also see https://github.com/knownasilya/ember-toggle/blob/simplify/tests/dummy/app/templates/application.hbs#L184 If everything looks good, I'll probably be doing a major release.

@knownasilya tentatively looks okay. I like all the code deletion 😄 .

I think it should still use the ember input helper. Is there a reason we couldn't merge this PR?

Let me test out the new branch and if everything works, would you mind me doing a bit of cleanup, like using the input helper and submitting a PR or are you pretty set on things the way they are?
