fix: update DMPS InputChange event handler

In some configurations, the InputChange handler can throw
a null reference exception due to a Feedback for
the input that triggered the event not existing. The
event handler now checks for the existence of a Feedback
for the input that triggered the event prior to attempting
to call the `FireUpdate` method. Addresses #1136
