XML writtne successfully message once we don't overwrite auto.xml

'XML written successfully' message will appear during console installation after we choose not to overwrite existing auto.xml file. The file itself is not overwritten, but this message might be a little bit confusing for users.

Steps to reproduce:

• create some empty file
• run console installation
• choose to generate an automatic installation scripts, point the path to empty file
• choose not to overwrite the file
