[NDB_BVL_Instrument] Modify InstanceData Setting

[victori444]

Brief summary of changes

In the Instrument class' _save() function, updates the instance data if the instrument has an SQL table so that the instance data only needs to be saved once to calculate the correct score

This also updates the score_instrument.php script to resolve issue relating to the Query class update

Testing instructions (if applicable)

1. Run the scoring script for a candidate with the bmi instrument and verify that the scores are correct
2. Modify the instrument data in the instrument table only, not in data_instrument
3. Re-run the scoring script and verify that the scores are updated according to the changes made

I don't understand why you're doing this here. It seems to be duplicating line 855 but more inefficiently. I think you just need to update line 846 to fix the fact that it's not dealing with table data correctly?
