Calculating summary budget Total Sponsor Cost
Also include minor fix during testing to reset dialog.

It is invoked via saveBudgetPeriod in ProposalBudgetRateAndPeriodController
getBudgetCalculationService().updateBudgetTotalCost(budget)
Referring to login in 5.2.x we are not recalculating budget. All that we are doing in computing the total sponsor cost when it is a direct edit of these values in budget period.
I did not invoke this calculation in saveLine since that is a global/common method for all edit/save line item.
So calculating in ProposalBudgetRateAndPeriodController and invoking super to save line item.
