filterTrigger: filter negative trigger axis event after positive axis…

… detection

If filterTrigger detects a positive axis event on a common trigger axis while also
configuring a trigger, the next input event will be a negative axis press
(as the trigger needs to transition from >0 to rest at -32767).

Filter this negative event or else the next item in the configuration dialog
(typically "left thumb") will erroneously detect this as a separate event.
