Why:
* We should recalculate winners also when an incompatible investment is flagged as compatible again
How:
* Removing the condition to recalculate that was checking only for a winner investment flagged as incompatible
* Extending the Budget::Result model spec to cover that new scenario
Why:
* A incompatible investment can't be chosen as a winner
* When a winner investment is marked as incompatible, winnersmust be recalculated and it can't be a winner
How:
* Increasing existing scenarios to include a incompatible investment
* Adding a new scenario where a winner investment gets flagged as incompatible
