'filtered:add' event is triggered before the collection is filtered

[mishamaliga]

The filtered:add event is triggered in addFilter method, but addFilter method is executed before execFilter.

filterBy: function (filterName, filter) {
    if (!filter) {
        filter = filterName;
        filterName = this.defaultFilterName;
    }
    addFilter.call(this, filterName, createFilter(filter));
    execFilter.call(this);
    return this;
},

I think that filtered:add should be triggered when the collection is already filtered.
