Hide Blockly on Success/Failure

Hiding Blockly the way that the closeBlocklyBtn functionality works. @BrettASwift @kadst43 
This is a view call and this code exists in the model. It may work, but it is not "right." I tried `context.blockly_activeNodeID = undefined` earlier and it didn't seem to work, but maybe I was testing it wrong. Try that and let me know if it doesn't work.
