fix(dropdown): dont trigger onchange event on initiaload when values …

…are given

When values are given on initialization of a dropdown, all entries which have a selected attribute set will trigger the onChange event

The already existing fireOnChange setting does not cover this situation to prevent the callback.
In comparison: When a dropdown is just converted from a select and those option values do also have the selected property set, then the onchange does not happen, so the behavior does not match, but should.
