Steps to reproduce:
1. Open QA attached project
2. Build the project using the "build/build.bat" (Adjust Unity.exe path to match setup).
3. Open the built game
4. Notice that the sprite using point filtering
5. Open the project in editor
6. Observe the sprite using bilinear filtering while the editor is on stop.
7. Press play and observe the sprite is using point filtering in play mode because unity switches using the previously packed sprite sheet instead
8. Change any of the sprite import settings causing the sheet to be repacked in editor
9. Press play and observe the sprite getting fixed

Expected result: Building Legacy Sprite Atlases in batchmode with -nographics should not result in Point sampled Atlases
