Transforming the values of duplicated instances throws `[PathTracer] RemoveInstance job with hash: [hashID] failed with exit code 1.` error in the console

Steps for reproduction:
1) Download the project below and open the scene `test`
2) Find the GameObject `Plane` in Hierarchy and select it
3) While it's baking, duplicate it four times
4) In Hierarchy, select all the duplicated items (i.e. Plane, Plane (1), Plane (2) and Plane (3))
5) Duplicate them
6) Select and move the duplicated items (i.e. Plane, Plane (1), Plane (2) and Plane (3)) below the other GameObject group
7) Start rotating these selected items
8) Observe the errors in the console

- Regression introduced in 2018.2.0a1
