Expected Behavior

When you save the workflow, the seed should remain the same. It should only change before each generation if set to randomize in control_before_generate mode.

Actual Behavior

When the seed is set to randomize in control_before_generate mode, everytime you save the workflow, the seed get changed.

I just wanted to separate the "saved/unsaved status" issue from this one to make @huchenlei happier! 😉
