[BUGFIX #17529] Refactor get to return object or path

[eplata31]

I tracked issue #17529 and as suggested on the thread, it worked on the get property.
I wrote a new test based on the one from jasonmit and got it to pass, also all other test passed

Hope this will help, but any comment, suggestion or advice is welcome with open arms.
I am kind of new in the open source world so I hope I follow all of your contributing guides well but if I didn't it will be awesome if you could point out what I missed. Thanks :D

I'm not sure we should incur extra overhead for this, I think supporting periods in keynames was actually a bug and wasn't really intended behavior.

In dev mode, might be useful to throw with a helpful error message. It's not immediately clear what happened for those that do hit this while upgrading their apps. I can help land that if there's buy in.

I agree with @jasonmit and also it will be good to close the related issues to avoid confusion and extra work.

@pzuraq dot notation objects are fairly Common and i dont see a reason to let ember Break on a valid JSON

Sorry for the long turnaround! I think the ship has sailed on this 😅 We are trying to move off of EmberObject overall, too.
