Subject: [PATCH] Shape Healing - Crash in
 ShapeConstruct_ProjectCurveOnSurface::insertAdditionalPointOrAdjust() (#1267)

To input parameters of ShapeConstruct_ProjectCurveOnSurface::insertAdditionalPointOrAdjust() new arrays were assigned. The size of new arrays are guaranteed to be 1 element larger that original array. NCollection_Array1::Assign() is guaranteed to throw exception when arrays size mismatch. So, given that assignment code is reached, function will always throw.
Fixed by calling move assignment instead - size mismatch is allowed in this case. Also it is more optimal.
