Whenever an SSH item is inherited from a template, any attempts to update the User name or Password are ignored. After pressing the update button and reopening the item, the inherited User name and Password are still there.

Steps to reproduce:

1. Apply a template with an SSH item on it to a host
2. Open the host
3. Open the SSH item
4. Overwrite the User name and/or Password fields
5. Press Update
6. Open the SSH item again

Result:
The SSH item still uses the inherited User name and Password
Expected:
User name and Password should have been overwritten
