Move actuator to waiting location after tests

As is, the finger actuator will stay in the last location used during a
test case, which may be inconvenient for the operator.  Instead, move it
to the standard waiting location above the top left of the screen.

BUG=b:148627899
TEST=Run tests and observe that actuator moves to waiting location
