GUVNOR-2128 - Guided Score Card - Facts with more than one attribute are...

... now correctly saved and retrieved
we do not need the data type as we only need the FieldName to match. 

The issue with the previous code was that the dataType was "int" in the scorecard model and "Integer" on the UI side. Hence the previous #710, was failing. The index was always 0.

Now with the changed code, we only look for the field name and set the index to the correct position.
