Empty #region for generated Python tests

[tyuldashev]

Description

For each function under test there is one #region with name and another one without.

To Reproduce

Steps to reproduce the behavior:

1. Generate test for some Python function
2. Open generated test file

Expected behavior

All existing regions have names

Actual behavior

For each function only one region has name and second one is empty

Visual proofs (screenshots, logs, images)
Sample of such test file, note that second one has nothing after # region

class TestTopLevelFunctions(unittest.TestCase):
    # region Test suites for executable fractals.mandelbrot.get_distance
    
    # region
    
    def test_get_distance(self):
...

Now it becomes "# region FUZZER"
