Reactivating the algorithm manager does not work

[ymollard]

After deactivating the algorithm manager with /algo_control_switch_srv, it always fails with answer.result=1.
Same thing with manual call rosservice call /algo_control_switch_srv "mode: 0" that returns error 1.

As a consequence, recalibration is not possible after the joint state action server has been started at least once: https://github.com/ymollard/eDO_control/blob/master/src/edo/states.py#L257
