WebUI `Edit running load test` not carried `user_classes` when enabled `--class-picker`

Describe the bug

1. Run the web ui with option --class-picker, and it contains two userclass scripts(locustfile1.py,locustfile2.py), here we only pickup the locustfile1.py as the locust userclass
2. When the script is running, from the top right click the Edit running load test and it only show custom the concurrent user, spawn rate and host, no options of UserClasses and ShapeClass
3. Then click the Start swarming button

Expected behavior

It should only run locustfile1.py user class

Actual behavior

It had run all the userclasses, including locustfile1.py and locustfile2.py

Steps to reproduce

See above description

Environment

• Locust file contents (anonymized if necessary):

@mikenester Can you maybe take a look at this?

Might be hard to do, but at the very least we should grey out the User & LoadShape options in the “edit running test dialog” to indicate that they cannot be changed.

Yeah i can take a look a little later today
