Remove deprecated Ember.copy

[nlfurniss]

Since this isn't using Ember.copy to copy deeply, this should be fine.

[rwjblue]

I haven’t dug deeply, but I believe CI is failing here due to Ember 2.4 not having Ember.assign. There is a polyfill you can add as a dep though...

[nlfurniss]

@rwjblue how do you feel about dropping 2.4 and bumping the major? It's so old at this point that I think that'd be better than adding more code

[rwjblue]

Yep, seems totally fine to me also. I’d go all the way to 2.18 as minimum I think...

[nlfurniss]

Not sure if I made a mistake or this is just a CI failure...

[rwjblue]

ember-lts-2.18 isn't in config/ember-try.js (thats what the error is saying). When you add it, could you also delete 2.4/2.8?

[nlfurniss]

Ok we in business!

Thanks for the upkeep effort @nlfurniss! 😄

@rwjblue, would you take the reins on ushering this in? I've been away from the project for so long now, I hardly feel in the right to do so. Do you have all the permissions you need?

[rwjblue]

I just merged #125 which handled the ember-try things here, would you mind rebasing (which will drop out the .travis.yml and config/ember-try.js changes)?

[nlfurniss]

Rebased and ready to go :-)

[rwjblue]

Thank you @nlfurniss!
