    libvirt-sys-importer: constructor throws all errors
    
    Constructor should simply throw all errors at the caller, not just the
    one it creates itself.
    
    This simplies the code a bit and fixes he issue of 'Import 0 boxes..'
    button showing up in the wizard source when connection to system libvirt
    fails.
