Summary	0003863: Point-on-line not correctly auto-removed when redundant
Description	When "Auto Remove Redundants" is enabled, a "Point-on-line" constraint isn't removed when redundant if the superseding constraint is applied in continue mode. Solver displays an error message about redundancy instead. Everything becomes OK if a sketch item is dragged. It works well in preselect mode. It seems that this faulty behavior is specific to this "Point-on-line" constraint.
Steps To Reproduce	Create a new sketch and check "Auto Remove Redundants" is enabled Create 2 lines (let's call them A & B, and their respective endpoints x.1 & x.2) Select line A and endpoint B.1, then add a Point-on-line constraint (Preselect mode): Select endpoints A.1 & B.1, then add a Coincident constraint => Everything's fine, Point-on-line constraint is removed Come back to the state at the end of step 3 (Postselect mode): Select Coincident constraint (w/o anything selected), then click on A1 & B1 => Ouch ! Sketch isn't updated and solver displays "Sketch contains redundant constraints". Now just drag any line/endpoint with the mouse => Sketch is now updated and redundant constraint is removed
