Generate referenced enum defaults correctly

[sdboyer]

Currently, when there's an enum with a default value that's referenced, we generate the reference to it like this:

CUE	TS
package cuetsy AutoCamel: *"foo" | "bar" @cuetsy(kind="enum") Ref: { ac: AutoCamel } @cuetsy(kind="interface")	export enum AutoCamel { Foo = "foo", Bar = "bar", } export const defaultAutoCamel: AutoCamel = AutoCamel.Foo export interface Ref { ac: AutoCamel } export const defaultRef: Ref = { ac: "foo" }

This fails typechecking. The default should be:

export const defaultRef: Ref = {
  ac: AutoCamel.Foo
}

This (disabled) test contains a more exhaustive set of cases to check, but they all ultimately amount to the same problem.

Note - OP is not actually quite true. We do fine with the basic case. Things get screwy when we try to rely on attributes through various combinations of intermediate unification and reference.
