Event tab should error check for required fields before allowing you to exit

[brianscott]

Hello Alteryx Dev Gurus - 

I made an event to email me when there was an error at run time.  But I did not populate the 'To' field.  (I know!)  The process borked soft and shows as an error in the results queue when a customer noticed there was no data.  This is one of the simple ones.  

Thanks!
