Fix T94837: curve tilt on a 2-point-curve is wrong
2-point-curves are treated separately from 3plus-point-curves (assume a
lot of the twisting reduction can be skipped, so there is a dedicated
function for single segment curves).
And while using the 3plus-point-curves function [`make_bevel_list_3D`]
would actually work in this case, the dedicated function
`make_bevel_list_segment_3D` would only consider the tilt of the second
point and would just copy over the quat to the first point as well. Dont
see a reason for this, now consider the first point's tilt as well.
