IntGdiAngleArc resets pPath->newStroke

After drawing a still open path with AngleArc, the internal field newStroke is reset because of a call to IntGdiMoveToEx (which calls PATH_MoveTo to reset newStroke). This results in a (unneeded) MOVETO path operation if the path is continued afterwards.
See gdi32 path test function test_anglearc for a testcase for this.
Removing the IntGdiMoveToEx call fixes this problem and the related 11 path winetest, but i'm unsure why it was added - since the final point should be reached within the PATH_ARC function.

Still the comment indicates some importance of that call (\reactos\subsystems\win32\win32k\objects\arc.c:298):
IntGdiMoveToEx(pDC, x2, y2, NULL); // Dont forget Path

Maybe PATH_MoveTo in IntGdiMoveToEx is expendable?
