Title: Make specific transmission interfaces proper types.

- Proper types instead of namespaces allow to provide less cryptic feedback.
* Using typedefs:
"transmission_interface::TransmissionInterface"

* Using a new type:
"transmission_interface::ActuatorToJointPositionInterface"

- Added error message printing to tests for manual inspection.
