Eugen's Description:
LessInteraction#expects will set up a getter for each parameter that is passed into it.  This allows interactions to override such getters.
  Steve's Description:
When you have a method defined in your interaction that is the same name as an expected parameter (using expects) the parent interaction will override your method and your method will never be called, only the getter for the expected parameter will be called. This commit fixes that.
