General Cleanup

This fixes a few issues:
1. When logging in, try to load the store then init if it doesn't exist.
2. Fix receptionIdentity return on LoginLegacy returning Transmission, not Reception, elements
3. Call NewStateLegacy inside the LoginLegacy object, which would otherwise break compatibility with existing mobile client stores.
