reboot_gnome and shutdown tests failed because they required to match auth dialog on SLED
SLED build 0419 all reboot_gnome and shutdown tests failed:
[eg:in reboot_gnome]I have researched the autoinst-log and the video, found that after 'assert_and_click' the reboot button
openQA should ran wait_boot, but it actually ran assert_screen(mustmatch='reboot-auth', timeout=15)
so all of these tests are failed.
