bpo-46755: Don't log stack info twice in QueueHandler

[emontnemery]

In QueueHandler in logging, the stack info (stack_info) was being appended to the message twice after bpo-31084. This clears LogRecord.stack_info in the QueueHandler.

In your example the line

_LOGGER.error("Hello", stack_info=True)
Produces an error that says not found in latest version 3.12.
Also, tried a few examples using exc_info=True but could not find any issues.
Do you have an example that shows this issue?

Actually, I am able to reproduce this. The issue had dropped off my radar, but it's back on now.
