ProjectPoints2 fails for 3xN object points / 2xN image points (Bug #1550)

I couldnt find this elsewhere, so apologies if it's already been fixed. Applies to Linux x64, Opencv 2.3.1, svn6514

In the API, ProjectPoints2 claims that object points can be 3xN or Nx3 (for one-channel), likewise image points can be 2xN or Nx2.

This python code, taken from https://code.ros.org/trac/opencv/browser/trunk/opencv/tests/python/test.py?rev=2296, succeeds in one case and fails in the other (commented lines).
