[Jazzy] Redeclaration of parameter

System: Ubuntu 24.04 on Docker
ROS distro: Jazzy

When running the [project_dji_tello](https://github.com/aerostack2/project_dji_tello/tree/main), the following parameter declaration:
https://github.com/aerostack2/as2_platform_tello/blob/5dfa6a0722ee8a628935bc2d9f10405194007441/src/as2_platform_tello.cpp#L93
causes:

Commenting it fixes the issue and the system works perfectly.

This is due to initializing the `tf_handler`:

Before declaring the parameter, so this condition:

returns false.
