`TelegramClient.edit_2fa` returns invalid value when disabling 2FA with invalid password

[nimaxin]

Code that causes the issue

async with TelegramClient(...) as client:
        result = await client.edit_2fa("invalid password", None)
        print(result) # True

Expected behavior

I encountered an issue when attempting to disable 2FA on an account that does not have 2FA enabled. The method TelegramClient.edit_2fa returns an invalid value when I pass an invalid password instead of None as the current_password parameter.

Steps to Reproduce:

• Use an account that does not have 2FA enabled.
• Attempt to disable 2FA using TelegramClient.edit_2fa, providing an invalid password instead of None as the current_password parameter.

Actual behavior

It should return False
