fix(belongs-to-many): properly pair association based on the through …

update should pass options to set

…ons.through, not a reference

Currently the options are not passed along, which breaks ssaclAttributeRoles and might break other plugins.
Generally all options should just be propagated (unless they need to removed cause they will break the method).

The code would previously pair association based on the through.model argument of the original options.
However options.through.model would generally be undefined since users usually just pass through: Model and the normalization to through.model
actually happened on association.through rather than options.through.
Normalization now happens on the options set before being assigned to association.through
