Accounts; saving a Quote fires script event "StatusChangePost" but parameters are incorrect

Saving a new Account as a "Quote" should fires a number of script events.

One of these is the "StatusChangePost" event. This event passes in the Account Status before and after the Account was saved.

In this case, ie a new Account saved as a Quote, these should be isefinAccountStatus.None and isefinAccountStatus.Quote. However, they are incorrectly sent as isefinAccountStatus.Quote and isefinAccountStatus.Open.
