_physijs.touches are not disappearing after collision with dirty-positioned meshes.

Hi,

I have two PhysiJS.BoxMeshes catching one PhysiJS.SphereMesh between them. Boxes are controlled by plain animation, so I had to set __dirtyPosition & __dirtyRotation to true. PhysiJS.BoxMeshes have zero mass, otherwise sphere just falls through them. After I take away those Boxes from the Sphere, Sphere still has two ._physijs.touches and unable to fall down with the gravity force.

Example is here http://test.yoshi.tk/

Thank you.
