Ensure DateFiltering is included in models

[tubbo]

To avoid a missing by_updated_at method error in tests, explicitly decorate the models that may autoload ApplicationDocument prior to the API's engine initializer getting called.

NOTE: This change should be more apparent in mega-build or an actual app, since the tests don't fail when running locally.

So the actual issue is that any model loaded during initialization isn't going to receive this decoration. Here was the original fix in base: https://github.com/workarea-commerce/workarea/commit/5b0663628480533a78298ebd06ee37fec5a2e8aa

@bencrouse so can this be backported to v3.4 or is there something in there that's 3.5 specific? 3.4+ is what this version of the API depends on.

[bencrouse]

I don't believe this could be backported. I remember thinking the API-change was the only way I could think of to fix it, so it would have to be fixed in v3.5.
