`{{#each}}` without any params causes error

This line broke the inspector's test:

This was caused by this line in the inspector's tests. While it's an invalid usage and you should probably get some error either at runtime or build time, the way it fails now is unexpected.

Dang I just debugged this same thing 😭

@mixonic sounds correct to me. Feel free to remove it again against master when you get a chance

Resolved.
