Fixed adding a Bezier curve to wxGraphicsPath with Direct2D renderer.

Browse Source 
When current point is not set before the call to wxGraphicsPath::AddCurveToPoint() then it should be set at first control point prior to adding a curve (function should behave as if preceded by MoveToPoint).

Closes #17526
