memory spike running unity with -testability

Looks to me like a 2MB memory spike when the Greeter is introspected. This
is probably caused by the tree traversal done to find the greeter in the
first place.

We should:

1) make sure autopilot is generating absolute queries only, so we don't
load the entire tree into memory at any point.

2) Look at autopilot-qt for places where we can reduce the class memory
footprint. I suspect we can make a few improvements there.

No, not really. Autopilot should be generating absolute queries in most
cases anyway, depending on which methods you call. We just need to make
sure that's still the case.
