Change user.config to resetting the master password now invalid? (Version 2.6.1 2.7.0)

By #236

1. I change the `user.config`:
C:\Users\w\OneDrive\work\.wind\profiles\default.v10\user.config (Onedrive sync folder)
```json
{
"application.language" : "zh-CN",
"terminal.reimportShellSessions" : 2,
"terminal.text.hiddenMargins" : [ "symbol", "timestamp" ]
}
```
2. Find the path `.wind/profiles/default.v10/terminal/user.sessions` and delete `session.autoLogin`
3. open the Windterm
4. Ctrl+Alt+L (Windows)
5. change master password
1. oldpassword nothing
2. new password input
3. submit
4. notice change master password error

### Test
1. Windows Windterm 2.6.1 the user.config can't not reset password.
5. Windows Windterm 2.7.0 the user.config can't not reset password.
6. Macos Windterm 2.6.1 the user.config can't not reset password.

@kingToolbox Please help me, thanks

Reproduce the password-change failure using the shown user.config path and the terminal/user.sessions file, including removal of session.autoLogin and the Ctrl+Alt+L flow. Compare the reported Windows and macOS behavior in WindTerm 2.6.1 and 2.7.0. Done means changing the master password succeeds after the described reset state.
