test: add test to check sticky events order

Browse source 
Sticky events pushed on an unlinked pad should be stored on the pad. When the
pad is then linked and an event is pushed, the event should be merged with the
already existing sticky events and then the sticky events should be pushed in
the order that they were originally pushed.
