The results of the testability explorer "generally" don't get published within
Hudson.
Testability-xml-reportfiles are not saved in the jobs' builddirectory (in
HUDSONHOME) where all the other xmls go.
There's no errormessage nor a trendgraph. There's just the testability-paragraph
on the job-configure-page and the headline for the trendgraph on the
job-status-page.
