Default Interest; change to Monitor Category "In Default" logic when calculating Default Interest

A change has been made to the logic behind Monitor Category changes and if an Account is "In Default" on a day when calculating Default Interest.

Previously, if the Account was "In Default" at any time during a day it was treated as "In Default" for that day.

This has been changed so that only the end of the day "In Default" status is used.

NOTE: If you change an Account's Monitor Category to "In Default" and wish to reverse this, instead of doing another Monitor Category change clearing it, consider cancelling the initial change instead.
