Apps with non-lower name seem to be not supported

Hello,
looking through wagtail-transfer to integrate it into existing project. However, looks like the code assumes model names normalize to lowercase, which isn't the case with my project - it has been set up with camelCase app names, and migrating is simply not worth the pain.

Since relevant AppConfig methods are case insensitive anyway, is it possible to just not do this normalization?
