Re-enable tests when intra process manager takes an allocator again #85
Description
The test was disabled in #84 and it needed to be disabled because the refactored intra-process manager in rclcpp unfortunately did not have the ability to control allocations in its merged state, see:
However, the plan is update that implementation soon to again take an allocator and allow for complete control over all allocations. At that time, the disabled test should be re-enabled.
Also, at the same time it would be a good idea to refactor this test to use https://github.com/osrf/osrf_testing_tools_cpp#memory_tools instead of a custom new and delete as that approach has limitations. Also to consider how it may not work correctly for all rmw implementations, see:
