test: Make touch test reflect new ability to realloc touch array [v2] 

Threaded input allows the input code to call malloc while processing
events. In this case, that's in the middle of processing touch events
and needing to resize the touch buffer.

This test was expecting the old behaviour where touch points would get
dropped if the buffer was full. The fix is to check for the new
behaviour instead.

[v2]

 * make sure two finding two equivalent touches return the same touch
   object

 * check to make sure the queue resizes by the expected amount
