Verifying events from TouchInteractionService

There is a guaranteed order in which TIS events will be registered
relative to other TIS events. However, relative to the touch events
arriving to the activity, TIS events can come in any order.

Now the event checker verifies 2 independent ordered event sequences:
from TIS, and “the rest” (Main).
