Don't call new A

[jacobq]

This addon is causing the following error to be thrown when used in an Ember 3.13 app (and likely with earlier versions too):

Error: Assertion Failed: You cannot create an Ember Array with new A(), please update to calling A as a function: A()

The fix should be trivial (remove new).
See https://deprecations.emberjs.com/v3.x/#toc_array-new-array-wrapper

Here is the offending line:

ember-composability/addon/mixins/parent-component-support.js

Line 22 in 18c663d

return new A(comps && comps.size ? this.get('_childComponents').list : []);

This is related with this problem I'm having with the library ember-cli-materialize, don't know how to use this changes.
