Final Complex parameters not updating after compilation

[tinrabuzin]

Description

When changing the real and imaginary variables after compilation, the complex number does not change.

Steps to reproduce

If one compiles the example model below, and after compilation tries to change a or b, this change is not reflected in cplx1. If I am not mistaken, cplx1 should be updated accordingly. At least that is what happens with Real parameters.

model example_complex
parameter Real a=1;
parameter Real b=1;

final parameter Complex cplx1 = Complex(a,b);
equation

end example_complex;

I am running OpenModelica v1.16.2.

My fix is causing some minor changes in some of our test cases. It's probably fine, but I will do some more testing to make sure before merging the PR.

I found another related problem for the following model

model test
parameter Real phi = Modelica.Constants.pi/4;
final parameter Complex x = Complex(cos(phi),sin(phi))*1;
end test;

If *1 is removed from the binding expression, the change in phi is reflected. With *1 included, x is not updated.
