Don't recalculate counters in Execution if value is NOT_APPLICABLE

[petertrr]

• Store aggregated metrics in Execution excluding NOT_APPLICABLE metrics from individual test executions (until we can calculate scores for other types of plugins too)
• Change logic of dispaly on frontend: don't calculate metrics only if all test executions under an execution are NOT_APPLICABLE; otherwise use filtered data from Execution
