ApiLayoutController::get should not default model to stdClass

🐛 Once previewed in XB an entity with no changes will still show up in "Review x changes" Active introduced this method and possibly missed in the refactor

This is needed to ensure an empty model is json encoded as {} and not []
I think the calling code should cast it to an array.

We do this on line 366 but missed line 344, I'll add a test and a fix.

Added a test to reproduce the scenario, which is unique in that there are enabled global regions but they're all empty.
Fixed per #6

Seems like it'd be a common place for anyone starting fresh with XB and just turned on their global regions. Great catch

Only when 0 Block config entities existed! See PageRegion::createFromBlockLayout() + experience_builder_form_system_theme_settings_submit()

Nothing to do here: one-line change, expanded test coverage by @larowlan ⇒ 🚢

😂 par for the course for me to hit that oddball edge case.
