Flaky windows test test_node_info_clients

[sloretz]

Bug report

Required Info:

• Operating System:
  • Windows 10
• Installation type:
  • source
• Version or commit hash:
  • 8bf120b
• DDS implementation:
  • rmw_connextdds
• Client library (if applicable):
  • N/A

Expected behavior

All tests would pass

Actual behavior

One test fails in the Windows repeated job.

Additional information

I'm not sure what function is actually failing because of how the test is written. It's failing here. I would recommend reorganizing test_graph to give more info about these flaky failures.

It could be any one of these functions.

• rcl_get_subscriber_names_and_types_by_node
• rcl_get_publisher_names_and_types_by_node
• rcl_get_service_names_and_types_by_node
• rcl_get_client_names_and_types_by_node

Whatever it is, the function is returning RCL_RET_NODE_NAME_NON_EXISTENT

Same test, but different issue from #855
