[Octane] Ember Data model @attr doesn't track

[wongpeiyi]

I'm not sure if this is more an Ember Data issue or an unimplemented feature etc

I have a getter that computes off a DS @attr. When the attr changes, the template updates correctly once, but if it changes again subsequently the template doesn't update.

Switching from @attr to @tracked works perfectly however, and so does displaying the attr directly in the template. The only failing case is a getter based off an attr.

I've confirmed that this is an issue with CPs in general, not just @attr (which is implemented as a CP under the hood). I've also confirmed that the work done in #18223 fixes this issue, so I'll add a test to that PR to ensure we cover it.

Thanks @pzuraq, looks like it's fixed in master after the merge
