filterBy needs .@each when composed to see updates

It seems that without a .@each.<keytofilterby> the result will not update on changes to the key.

I have a reproduction of the bug here: https://ember-twiddle.com/d6a67b62d1a193fbbdaa67fbd5092d14?openFiles=controllers.application.js%2C

I don’t really know how to work with ember-macro-test-helpers so can’t really build a failing test case. But hopefully this twiddle be enough.

I’ve discovered that my issue is a separate bug: array macros fail with Array-like objects such as DS.ManyArray.

I’ve reported it in #423, covered with a failing test in 1e55173 and proposed a fix in #424.

When I do filterBy("reviewers", "voted", true) with ember-awesome-macros, then the raw value of $E.voters._dependentKeys[0] is `“[e-mail]”.

But when I do voters: filterBy("reviewers", raw("voted"), true) with ember-awesome-macros, then the raw value of $E.voters._dependentKeys[0] is `“reviewers”.

I even tried voters: filterBy("[e-mail]", raw("voted"), true) and it still didn’t work.

I tried the ember-macro-helpers#composing-class-computed branch from https://github.com/kellyselden/ember-macro-helpers/pull/149 and it did not help.

I’ve been slowly converting my app to ember-awesome-macros (because I’m a huge fan), but this bug burns badly. I wonder how many regressions my app has already?

@kellyselden, which other macros may be affected by this?

Will you accept a PR that adds checks for .@each. inside _dependentKeys[0] to tests of every array macro?
