Expected Behavior

One can create a goal with type "send an event" and afterwards switch the type successfully

Current Behavior

• create a new goal with "send a goal" set
• tick Use the event value (if it exists) as the goal conversion revenue.
• save the goal
• edit the goal
• change the type to "visit a given URL"
• notice how the "Use the event value..." UI dissapears, but still seems to be ticked
• save the goal
• see 'useEventValueAsRevenue' can only be 1 if the goal matches an event attribute.

Possible Solution

Whenever the UI is hidden, the value should also be set to 0 as 1 doesn't make any sense anymore
