Fix jobs table when jobs have different config keys

If we have 2 jobs within 1 build, with such config values:

    { rvm: 'jruby-head', jdk: 'oraclejdk7' }
    { rvm: '1.9.3', jdk: null }

We should return jdk in configValues for second build, even if it's not
present. Otherwise table rows may be missing.

(closes #28)
