Fix T38407: Bone roll calculation flips local axes at wrong rotation angle 

Just remove that rotation special case for now, at least fixes the glitch along Z axis when rotating around Y axis in report.

Anyway, there is no reason for such special handling, we do not have real rotation in editbone...
