Lacks test for attributes in twinglydata element

[walro]

We have no test that checks that we correctly parse and extract the numbers from the twinglydata element:

<twinglydata numberOfMatchesReturned="3" secondsElapsed="0.148" numberOfMatchesTotal="3">

I think current issue could be closed with #31 also.

Please check following lines in tests.

I'll close this as it was fixed by @xSAVIKx in #32 🎉
