The BaseUser table hashes passwords before storing them in the database.

When we create a fixture from the BaseUser table (using piccolo fixtures dump), it looks something like:

{
    "id": 11,
    "username": "bob",
    "password": "pbkdf2_sha256$10000$abc123"
}

When we load the fixture (using piccolo fixtures load) we need to be careful in case BaseUser tries to hash the password again (it would then be a hash of a hash, and hence incorrect). We now have additional checks in place to prevent this.

Thanks to @mrbazzan for implementing this, and @sinisaos for help reviewing.
