Fix duplicate self parameter in Bundle easyblock

[Flamefire]

Fixes #3778

super().x() already passes self so this was equivalent to EasyBlock.prepare_step(self, self, *args, *kwargs)

Also fix the name in check_checksums as that was very confusing, especially next to each other:

        for comp, _ in self.comp_instances:
        ...
        for _, comp in self.comp_instances:
