    dav: properly handle cancellation during mounting
    
    If the user cancels the authentication dialog during the mount
    operation, we should catch that case and instead of returing
    G_IO_ERROR_FAILED we should G_IO_ERROR_FAILED_HANDLED. This will
    prevent an (expected) error being back to the user. This is in
    line with what other backends do in the same situation.
