Restore command asks for password although none specified during backup

[Ph-St]

Test environment

• Manjaro 24.2.0, pymobiledevice3 4.16.1
• iPhone12,8, ios 17.6.1

Describe the bug
The restore command reports that a backup that is encrypted and that I should supply a password. However, during backup, I didn't ask the backup to be encrypted and did not specify a password. I'm not sure whether the backup was actually encrypted or whether it is not encrypted but pymobiledevice3 asks for a password nevertheless.

To Reproduce
Steps to reproduce the behavior:

1. I ran
   pymobiledevice3 backup2 backup --full iphone_backup/
   it finished without error message.
2. I ran
   pymobiledevice3 backup2 restore iphone_backup/
   and the response was
   pymobiledevice3.services.mobilebackup2[2812524] ERROR Backup is encrypted, please supply password.

Expected behavior
Since no encryption was specified or password supplied during backup, I expected that the backup would not be encrypted. In case it is actually not encrypted, I expected that the program would be able to restore the backup without a password.

Additional context
There is another weird behavior. If I run
pymobiledevice3 backup2 restore iphone_backup --password
the response is
Error: Option '--password' requires an argument.
So I tried to make another backup with a password and ran
pymobiledevice3 backup2 backup --full iphone_backup/ --password my_secrect_password
But the response to this was
Error: No such option: --password

Only the restore option requires a password, which can be an empty string. For creating a backup with password use the encryption subcommand which changes this setting globally and forces all created backups to have a password
