bug: Add recalculateActiveCoverInAsset to Cover contract

[MilGard91]

Context

There was a bug before when we did expireCover method, that we removed it from the bucket but didn't update the active cover amount, after that was fixed we have bad data in the contract. Calling this function will recalculate the amount by going through all the buckets and sum all the their amounts. Since year is the max period for cover buy, the 52 week/bucket constant was used.

Issue: #1049
