When running AppHarness or unit tests via pytest, delete duplicate state names (and basically redefine the state tree with the new class). In a previous patch i removed this bit of code (https://github.com/reflex-dev/reflex/pull/2227/files#diff-704efe440192781e072231490ac1d12defd1aba5f6debafbc7907eebcc2abcc7L304-L314). But it turns out to be necessary. So I restructured the duplicate name check a bit to indicate that this subclass resetting should only occur in testing modes, and expand a bit on why we're doing it that way.

rx.Statetorx.BaseStateand creates a base state(rx.State) for all client apps. With this approach every substate will be a child(or substate) ofrx.State. Also allows multiple inheritance fromrx.State:docs: reflex-dev/reflex-web#306
