Can transfer max amount after many blocks have been mined?

[shingonu]

expected revert scenario:

1. mint user's token amount
2. (after many blocks have been mined) approve users's token -> factor is increased
3. transfer user's max amount to other account (revert?)

I think we need to make test code about that and make logging about coinage.balanceOf(user) for each steps.

[shingonu]

uint256 rbAmount = _toRAYBased(amount);

I think we should delete above code in _transfer and _approve function.

but tot and coinage can't transfer token. so I think tot and coinage do not belong to this problem.
