Philipp Oeser 0e1440eefd Paint: Orbit around selection/stroke: remove redundant case 
Since rB8014180720d8, all paint modes support orbiting around last
stroke, so [a] the comment there is out of date and [b] the fallback
case of orbiting around the center will never be used (unless there is
no stroke information - but BKE_paint_stroke_get_average handles that
anyways).

Spotted while looking into T101766.
