Foliage painted on Mesh Terrain disappears after edits are made

Mesh Terrain recreates the visible section actors when edits are made, and those sections in the editor don't correspond to the ones at runtime, which breaks the ComponentId that the foliage system tracks

1. Create a level and mesh terrain
2. Paint foliage onto the mesh terrain
3. Modify(for example, sculpt) the area where you previously placed the foliage
4. Foliage won't be affected by the changes in the mesh terrain
