Exposing ID if actual contracts

[ali-bahjati]

declare_id exposes ids publicly and it might be misleading for users. It is a practice in sdks that they include their contract ID and consumers often check with that. In Pyth usecase it is unlikely that a consumer do that because usually they initialize their contracts with correct price account key and check against that.

We can keep it as it is, or move out test contract, or make it mainnet/devnet id.

Since we are not exposing it now I think we can close this.
