[16.0][FIX] logging_json: fix RecursionError

[sebalix]

Since Python 3.10, the use of threading.currentThread() is deprecated and generates a warning, and generating this warning log was in turn entering in the logging_json mechanism, triggering an exception:

RecursionError: maximum recursion depth exceeded while calling a Python object

This error could be related to queue.job stuck in the state Started on some projects (to confirm).

EDIT: I confirm that this was blocking some jobs. I don't know why they weren't put in a Failed state but instead were still in Started, I didn't check.

Traceback:
