Bug 1262109

when running a test, clicking the 'stop' button results in an AttributeError that is not handled.

redhat-certification-2.0-20150909.el6
redhat-certification-hardware-1.6.6-20150901.el6

no workaround yet

Steps to Reproduce:
1. install on a laptop system (with mandatory 'suspend' test)
2. create a certification with a host attached
3. run a test
4. click 'stop' to abort the suspend test (there's no other way to bypass it in the web ui).

Actual results:
Environment:

Expected results:
test stops, bypassing suspend test.
