[Crowdfund] Disable Migration from v1.0.0

[crnbarr93]

Description

Due to the scale of the restructure for the crowdfund contract we should disable migration from v1.0.x versions of this contract.

Implementation

Add an additional check in the migrate handler that checks state for the previous version (before it is updated by ADOContract::default().migrate) to ensure that it is not migrating from v1.0.0:

Acceptance Criteria

• Inability to migrate from andromeda-crowdfundv1.0.x contracts
• Testing to ensure this check holds

I wonder if we can maybe add a generic handler for something like this to our std crate? That way if we need to set a minimum upgrade version in any contract in future we have a simple method we can call.
