Use handler and unregister properties after test

In previous design, the listener still listen to gear event after it got
all expected events. In this case, if the tester change the gear before
quitting the page, the listener will get an extra event and throw
exceptions.
Use the countDownLatch to count the events and unregister the listener
after we got all events.
