Fix event stream in DragAndDropNotCancelledIfSomeOtherPointerIsPilfered

Before this CL, this test injected two POINTER_1_DOWN events in a row,
which is incorrect.

Fix this by sending the ACTION_MOVE event for the last injection.

Bug: 316915830
Test: add fatal log locally on double pointer add and then run the tests
Test: TEST=inputflinger_tests; m $TEST && $ANDROID_HOST_OUT/nativetest64/$TEST/$TEST
