When import .paper2dsprites file, always output warning log.

It seems missmatch URL TexturePackerPrefix and AppName with metadata.


 - PaperJsonSpriteSheetImporter.cpp
const FString TexturePackerPrefix(TEXT(""));

 - metafile
Steps to Reproduce
  1. Drag and drop with .paper2dsprites file at editor.

Then, warning output log.

LogPaperSpriteSheetImporter: Warning: Unexpected 'app' named '' while parsing sprite descriptor file 'Test'.  Parsing will continue but the format may not be fully supported
