Quality Evaluator - Fix Incorrect General KPI Values at Artifact Level

The current Spark job in charge of compute the KPIs is not working properly. The return model of the Quality Evaluator has several sections for the quality profiling information:

• at column level
• at artifact level, for General KPIs (num_rows, num_columns, position)
• at artifact level, for User Defined Rules

The information from the General KPIs at artifact level is not correct.
