Unwanted debug output when running unittests (again).

[ziesemer]

Type: Bug

Behavior

This is a near repeat of #24743.

Extraneous output is being included into the "Test Results" output when running Python tests using unittest (the "Standard Python test framework").

Specifically, the PROJECT_ROOT_PATH is set, using /... as cwd for execution payload is unnecessary and unwanted.

vscode-python/python_files/unittestadapter/execution.py

Line 377 in 3c0301d

f"PROJECT_ROOT_PATH is set, using {project_root_path} as cwd for execution payload"

Steps to reproduce:

1. Run any Python unit tests using unittest.
2. Observe the extraneous output in the Test Results output.

Diagnostic data

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
