testbot/web: Fix the $Task->TestFailures check.

If it has not been set to a numeric value, $Task->TestFailures is
undefined so comparing it to an empty string makes no sense.
Fortunately undef ne "" is false (as well as undef eq "") so the code was
doing the right thing and was not generating a warning since warnings
are not turned on.
