Description

Python test generation error is showing for quite simple python functions, including examples on utbot.org

To Reproduce

1. Install one of the latest plugin builds from main in IntelliJ Idea 2022.2.3
2. Install Python plugin from MarketPlace
3. Create a Python project
4. Add the following code to it:

def print_hi(name):
    # Use a breakpoint in the code line below to debug your script.
    print(f'Hi, {name}')  # Press Ctrl+F8 to toggle the breakpoint.

def div(a, b):
    return a / b

# Press the green button in the gutter to run the script.
if __name__ == '__main__':
    print_hi('PyCharm')

5. Press Alt+Shift+U in code
6. Select both functions and generate tests
7. Agree to install suggested requirements
8. Make 5-6 steps once again

OK, I reproduced this bug. It happens only at the first plugin running. If I restart IDEA after creating python project, I can generate tests
