[display] fix class path exploration removing remapped files (#7329)

The issue in the example was:

- explore_class_paths loop comes across flash.display.Bitmap (from std) and calls the callback
- the callback calls TypeloadParse.parse_module' on the file, but the package of the returned module is remapped to openfl.display due to --remap
- this then triggers the CompilationServer.remove_file call, removing the file from the cache

closes #7283
