wfreerdp-client: Handle credman domain qualified username correctly 

If credentials are read from the Windows credential manager, and the **username** contains the **domain** portion (`domain\username`), a connection couldn't be establish.
This PR parses the username and domain, sets the correct properties in the settings structure pretty much the same way the CLI args handling is doing.
