Dropdown: autoWidth property wrong name

[Menecats]

In the commit ccad045 has been inserted a typo during a copy-paste in the autoWidth setter method name.

Currently is utc it should be autoWidth.

    @Input() get autoWidth(): boolean {
        return this._autoWidth;
    }
    set utc(_autoWidth: boolean) {
        this._autoWidth = _autoWidth;
        console.log("Setting autoWidth has no effect as automatic width calculation is removed for better perfomance.");
    }
