--overwrite doesn't work

[Gajillion]

Describe the bug
partdb:backup option --overwrite should allow overwriting destination output file, even if it exists. Instead, backup fails.

To Reproduce
Steps to reproduce the behavior:

1. Run initial backup with /usr/bin/docker exec --user=www-data partdb php bin/console partdb:backup --full /var/www/html/var/db/backups/backup.zip
2. /var/www/html/var/db/backups/backup.zip is successfully created.
3. Run another backup with the same command.
4. Command fails immediately

 [INFO] Backup Part-DB to /var/www/html/var/db/backups/backup.zip

 The file /var/www/html/var/db/backups/backup.zip already exists. Do you want to overwrite it? (yes/no) [no]:
 >

 [ERROR] Backup aborted!

Expected behavior
backup file recreated in place with same name.

Server Side

• Part-DB Version: 1.11.3 (docker)
• PHP Version: docker installed version 4.1.27
• Database Server sqlite
