Avoid warning about use of uninitialized value

[Martchus]

The variable $testsuite_name might be undef if the spec is an empty hash leading to:

Use of uninitialized value $testsuite_name in hash element at /usr/share/openqa/script/../lib/OpenQA/Schema/Result/JobGroups.pm line 413.

We can just skip empty specs here avoiding the warning.
