Before this fix, we would have gotten:
public scala.Function0<java.lang.Object> Foo.x()

If the type of a
valis aTermRef, generating the generic signature based on the underlying type will produce the typescala.Function0<underlying>. The reason behind this is that during thegettersphase, the same symbol will now refer to the getter where the type will be=> <underlying>. Since theTermReforiginally intended to capture the underlying type of aval, we recover that information by directly checking the resultType of the getter.Closes #24553
