Hardcoded address error

Summary

In StableOracles, some addresses are hardcoded but incorrectly addressed.

Vulnerability Detail

There is an oracle for each collateral, each referring to several external addresses. However, the oracles do not work properly because their addresses are incorrect.

Impact

The oracle does not work, and important functions of the protocols that depend on it are not available.
