closes bookshelf#2007 - The attributes object can be modified within `triggerThen` through hooks. Sample scenario described here bookshelf#2007 (comment). - Recalculating 'attributesToSave' object in after-triggerThen step solves the syncronization issue because it is still based on model's `attributes` property (the reference is not lost)

Introduction
When model's
attributesare modified during even hooks, e.g.on('save'), changes are not detected and incorrectattributesare persisted in the db.Motivation
As described in the #2007.
Proposed solution
The keep
.attributesavailable for modification and avoid loosing reference to that object duringtriggerThenstage we could refetch attributesToSave through a method instead of keeping an object around.Alternatives considered
Alternatively we could be explicit about not allowing to modify
attributesdirectly by the bookshelf clients. This would mean forcing use ofset(sometimes withunsetflag) method on the model to do any modifications. This approach is rather inflexible and would require clients to modify code.
