Events listeners from all locust files being executed when running a single UserClass

Describe the bug

When running locust with the new class-picker feature to choose the class to be executed the event listeners from all files are being executed, not just the ones inside the same file as the picked UserClass. The use case for this is being able to use @events.test_start.add_listener and @events.init.add_listener to do independent setups for each test with the new class-picker.

Thread on slack for reference

Expected behavior

I’d expect that only event listeners inside the same file of the selected UserClass get executed.

Actual behavior

Event listeners of all files are being executed.

Steps to reproduce

1. Create two separated locustfiles (each one representing a different test)
2. On each locustfile add @events.test_start.add_listener methods to setup anything before test run
3. Execute the files in any of the ways below: a. By running locust with class-picker b. By running locust with multiple files and selecting the UserClass
4. Observe the events on both files being executed on test start

Environment

• OS: macOS
• Python version: 3.10
• Locust version: 2.12.0
• Locust command line that you ran: locust -f . --class-picker or locust -f scenario_one.py scenario_two.py ScenarioOneUser
• Locust file contents: https://gist.github.com/leonardoggallardo/db95cb365c9ec6f23f10247afe764d6a
