fix(specs): make sumOfMultiplierPointsIsMultiplierpoints work again

Browse Source 
This invariant failed as the prover started making wrong assumptions
about the relationship between anyone's account's `totalMP` and its
`balance`, as well as an account's `bonusMP` and its `balance`.

This commit fixes it by adding the necessary invariants to proof the
property.
