SharedProtoDatabaseClient inherited from UniqueProtoDatabase which was
potentially risky since we can accidentally use some of UniqueProtoDB's
functionality resulting in incorrect keys/entries from the database
because we're not stripping/adding prefixes.

We now inherit from ProtoDatabase to ensure that any functions added in
the future must also be implemented in SharedProtoDatabase.
