fix possible error when generating typescript definitions (#600)

small change to fix error when generating ros-gazebo messages.

ros-gazebo includes services that end with Request like BodyRequest and LinkRequest. This causes the check to determine if an idl is a service to fail as it only checks if it ends with Request.
