    libvirt-machine-props: Ensure name change is saved
    
    The two different UI components (name property and toolbar title) that
    can be used to change the name of machine were using two different
    methods to do so and hence changing the name from toolbar title wasn't
    getting the name change saved.
    
    This patch unifies the method to change the name and ensures that change
    of name is saved.
