Fixed topicName and topicDataType in fast rtps communicator

Alejandro Hernández Corderorequested to merge
ahcorde/performance_test:ahcorde/fix/fast_rtps_communicator_topic_name into master

As discussed in this PR https://github.com/ros2/performance_test/pull/6#issuecomment-598576045 we need to make this change to be able to communicate FASTRTPS when it launches perf_test with two processes (Main and Relay)

The code is registering one data type, and then creating publishers and subscribers with un-registered data types. The postfixes were just needed to be appended to the topic name instead of to the data type
