fix: revert if strategy contract does not implement method

[gabririgo]

resolves #396

📓 Overview

The governance proxy deployment should revert in case the input strategy contract does not implement the assertValidInitParams method. This is a remote scenario that only happens when a user accidentally inputs a rogue strategy contract address. However, as the deployment does not fail, it is an undesired behavior as the same user won't be able to deploy a governance with the same name. This is relevant for multi-chain governance.

• revert proxy initialization if the input strategy contract does not implement the method assertValidInitParams to prevent accidental governance proxy deployment with rogue strategy contract.
• assert pool initialization fails with either incorrect strategy contract or rogue init params
