When Ionic build with minifyjs option, the CircularRelationError will be emitted.

[JeongJun-Lee]

When I try to build with --minifyjs, it also emits circular relations error like this. The minifyjs option includes the mangling by uglifyjs. I think the TypeORM is not safe about this mangling process. But the mangling process in Ionic is default. Ionic itself includes this mangling process in production build process with --prod option.

ERROR Error: Uncaught (in promise): CircularRelationsError: Circular relations detected: e -> t -> e. To resolve this issue you need to set nullable: false somewhere in this dependency structure.

By this mention, typeorm/typeorm#2597, if to prevent mangling as the limitation of TypeORM usage in Ionic is correct, please add this limitation to document. thank you.
