Smart event not being sent to MQTT during detection delay after motion event
<!-- BUG REPORTS THAT ARE NOT FILLED OUT COMPLETELY WILL BE CLOSED AUTOMATICALLY WITHOUT WARNING AND WILL NOT RECEIVE A RESPONSE. THE FORM IS HERE FOR A REASON. :). -->
<!-- Please ensure you read the documentation before creating a support request, especially the Troubleshooting page. -->

**Describe The Problem:**
<!-- A clear and concise description of what the issue is. -->
If a smart event occurs after a motion event, during the event duration delay, the smart alert is not sent to MQTT

**To Reproduce:**
<!-- Steps to reproduce the behavior. -->
Set the motion zone larger than the smart detection zone. If a person/vehicle is moving on the street and triggers a motion event, a person walking into the smart detection area will not trigger a smart event that is sent to MQTT. Deleting the motion zone will allow for dependable smart detection, or making the motion event zone smaller than the smart detection zone.
