Why is there a leading slash?

[maxlein]

When starting robot state publisher with my urdf or also with the MARA robot one, I always have a leading slash in my frames.
Whereas when publishing dynamic transforms via tf publishers I don't have them.

ros2 run tf2_ros tf2_monitor

I found this error through debugging this and this error.

It's essentially a leftover from the original port. The slashes are removed in #126 .
