Data gathering bugs

[JamesArruda]

A state that is never used won't have recorded data.

class Cashier(UP.Actor):
   items_scanned = UP.State(default=0, recording=True)

with UP.EnvironmentContext():
    cash = Cashier(name="cashier")
    print("items_scanned" in cash.__dict__)
    >>> False

Either make the state's instantiation non-lazy or check for this condition in the data gathering code.

Also, the data gathering uses break instead of continue when a location state is reached. Correct that.
