Resharing a password protected folder by e-mail leads to an error and incorrect notifications

[AndrinS]

Steps to reproduce

1. Setup and share a folder to a group.
2. Switch to a user who receives the share.
3. Reshare a sub folder by e-mail.
4. Protect the folder with a password by showing more options.

Make sure the default sharing configuration is set:

Share by mail:

Checked: Send password by mail
Unchecked: enforce password protection

Expected behaviour

• Password will be accepted and the recipient will get another email with the password.
• The folder will be password protected

Actual behaviour

• Password will not be rejected: "The given object name is invalid"
• Multiple emails with the defined password are sent out.
• Folder is still unprotected.
