    input-sources: avoid unneeded status icon re-creation
    
    When we get sources-changed signal current source returned by
    gf_input_source_manager_get_current_source will be NULL and status
    icon will be destroyed. After that we will get current-source-changed
    signal and status icon will be re-created causing flickering effect.
    
    Fix this by not connecting to sources-changed signal.
