Istanbul: Else path not taken

[ghost]

There are a number of functions which not have else branch. Considers covering but that is not covered else branch in which case

setEndDate: function(newDate) {
    if (this._setEndDate(newDate)) {
        this._notifyOnPropertyChanged('endDate');
        this._notify('onEndDateChange', this._options.endDate);
        this._notify('onDateRangeChange', this._options.startDate, this._options.endDate);
    }
}

@xaircore have you tested a scenario where this._setEndDate(newDate) returns false? That's likely the "else path" it's complaining about.
