    libvirt: add a test to guard against set_host_enabled raising an error

    Commit cc70e3a adds a finally block to _get_new_connection to
    automatically disable the host if making a connection to libvirt fails.

    The set_host_enabled method currently swallows all exceptions which is
    good so it doesn't mask the original libvirt failure in
    _get_new_connection, but we need to have a test that makes sure that
    isn't unintentionally regressed. This patch adds the test.
