notifypi – failure to send email on falling edge

Description

A NotifyPI enhancement was released with 8.4 which added the ability to specify ‘when’ to send an email: ‘Alarm Starts’, ‘Alarm Ends’ or ‘Alarm Starts and Ends’). However, the ‘Alarm Ends’ selection was failing to send the email when the trigger event (alarm) duration was shorter than the ‘Send Rate Limit’.
If the event duration was longer than ‘Send Rate Limit’, the email was sent as expected.
