[Bug]: setting Sigma Churn has no effect in X/Y/Z plot

Is there an existing issue for this?

What happened?

After a recent update I noticed that Heun can no longer be used in conjunction with different Sigma Churn values in the X/Y/Z plot settings (it still works in the SD.Next fork).

Steps to reproduce the problem

1. Use "Heun" Sampling method, enable X/Y/Z plot script, set Sigma Churn to 100, render
2. With the same seed, set Sigma Churn to 1, render
3. Notice there is no difference

What should have happened?

Sigma Churn should effect the image

Can confirm, possibly related to #12356

FYI if your intent is to use higher values for s_churn, it is now supported in the UI via the s_churn quick settings entry. Previously you had to use X/Y/Z plot to get those higher values as the UI was limited to 0-1.
