Improve configuration on app launch/active (#821)

- Centralize context initialization/refresh in platform-specific app
delegates
- Prevent multiple calls to .onApplicationActive()
- Simplify local/remote profile fingerprint comparison
- Revert to always replacing Core Data entities
- The remote store somehow ended up having duplicates, which caused
repeated imports of remote profiles due to randomly different
fingerprints
- Optimize reload of in-app receipt
