Collapse migrations to avoid using deprecated fields

[falvaradorodriguez]

What is needed?

We need to collapse the migrations and start from a new point.

Background

After migrating some safe-eth-py fields for more efficient ones, the goal is to clean up the unused classes.

The problem now is that these fields are being used by the migrations and cannot be removed from safe-eth-py.

To solve this, we need collapse the migrations and start from a new point without these dependencies.
