`SimpleThruster` does not set thrust if there are no thrust limits set (the default)

[jrtcppv]

Describe the bug Setting the setpoint (thrust and torque) on SimpleThruster ignores the thrust if it does not pass the check for upper limit > lower limit. By default the limits are (1, -1), so by default setSetpoint ignores input thrust.

To Reproduce Steps to reproduce the behavior: Set the setpoint on a SimpleThruster without setting the limits first, the call getThrust() and the thrust will have not changed.

Expected behavior Setting the thrust setpoint should work when limits are not set.
