Refactor HistoryTest.cpp to use HistoryViewModel (from CalcViewModel) instead of CalculatorHistory (from CalcManager)

[rudyhuyn]

Describe the bug

All our unit tests related to the History function use CalculatorHistory while we should use HistoryViewModel to also detect bugs and regressions in our view models (some difference between the 2, the order is different for example). This modification will bring our unit tests closer to how we actually manage the history in the Calculator project.
