Incorrect code comments in the StandardBridge.sol contract

Summary

Incorrect code comments in the StandardBridge.sol contract.

Vulnerability Detail

The code comments for the bridgeERC20 and bridgeERC20To functions in the universal/StandardBridge.sol contract do not match the actual code. The comments say the bridge returns tokens to the sender if the bridging fails, but the refund logic has been removed since PR#3535.

Impact

Specfication error only.
