[Bug 1968537] [NEW] python3.10 clears cli history at exit

[Nicholas Guriev]

Public bug reported:

python3.10 overwrites the ~/.python_history file with line
'_HiStOrY_V2_' effectively clearing any command line history.

Steps to reproduce:

1. Run python3.10 interpreter, type there 'copyright()' command (with no quotes).
2. Exit by pressing Ctrl-D.
3. Run the interpreter again.
4. Press Up arrow to see previous command.

Expected behaviour:

1. You see early typed 'copyright()' in the command line.

Actual behaviour:

1. Nothing appears, CLI history is clean.

** Affects: python3.10 (Ubuntu)
     Importance: Undecided
