Sprite sheets with modified textures don't reimport correctly

Also reproduced in Main Promotable-CL-2479729

paper2Dsprites assets created from Texture Packer can no longer be reimported into the engine with version 4.7

1. Open QAGame Editor
2. Extract 'TexturePackerFiles.zip'
3. From the Extracted Files, import "cash.paper2dsprites" into the Engine
4. Save All
5. Extract 'TexturePackerFiles_02.zip' and overwrite previous files (2 files only overwritten)
6. Rick click the Sprite Sheet Asset in the Content Browser, Reimport

RESULTS: Texture and Frames are reimported incorrectly

EXPECTED: Adjusts be made for differing Sprite Sheet size automatically
