🐛 avoid accidental empty properties

[arlimus]

A friend accidentally the query (which we used pre v9) attribute for the property, instead of the mql field. This led to an empty property, which in this case is never valid. Properties must be non-empty.

Guarantee non-empty props + add more testing.
