In the desctrutor, `mAxisRoot` or `mCubeRoot` may have already been freed by Qt. In that case, a `isEnabled()` call will create a segmentation fault. By checking the axis mode, this allows to properly know which objects needs to be deleted. Fixes commit b578f1e

@nyalldawson I was a bit optimistic with my memory leak fix. It can cause a segmentation fault un some cases. This is a proper fix.
