Enable guards in junit tests

Flipped the flag(s) to enable guard checks in the various junit
tests for the Usecases and Frankfurt controllers.  Note: the guard
checks use the guard simulator.
Modified new actor code to not include operation history on first
"guard denied" report (i.e., make it work like usecases does).
