fix(ui): resets value in where builder when operator changes (#11136)

### What?
The list filters in the collection view allows invalid queries. If you
enter a value and then change operator, the value will remain even if it
doesn't pass the new value field validation, and an error is thrown.

### Why?
The value isn't reset or revalidated on operator change. It is reset on
field change.

### How?
Resets the value field when the operator changes.

Fixes #10648
