SI-5361 Avoid cyclic type with malformed refinement
The statement `val x = this` in the refinment type:
(new {}): {val x = this}
is lazily typechecked, in order to, according to the comment
in `typedRefinment, "avoid cyclic reference errors".
But the approximate type used ends up with:
Refinment@1(
parents = [...]
decls = { val x: Refinement@1 })
This commit eagerly checks that there is no term definitions
in type refinments, rather than delaying this.
This changes the error message for SI-3614.
