Fix T67876: 2D Stabilization doesn't compensate rotation in spacial cases

This was caused by 2D stabilization trying to be smart and lower weight
of tracks which are too close to the rotation center. This was causing
algorithm to ignore a single track which was set to constant 1 weight and
used for rotation compensation.

It is quite tricky to quantify this change without having comprehensive
regression suit, so can only hope that initial intention is still working
as expected.
