refact04.gms : Refactor suite test 4

Description

This test is the fourth one of the refactor suite. This is a quantitative test
of writing/reading a workfile with one large parameter.
There is an expected sequence when using this test:

1. Run this test with command line option "--before=True"
2. Modify and rebuild cmex
3. Run this test without command line option
