fix(Input): remove duplcated 'onChange' handling

[kuzhelov]

Currently for each change of the input value we have onChange handler logic being called twice. This is happening due to the same event handling function is provided both for <input> DOM element, as well as for the wrapping component (default is <div>):

renderComponent({ ElementType, classes, styles, variables }) {
   ...

    return (
      <ElementType className={classes.root} {...restProps} onChange={onChange}>  // <----- HERE
        {createHTMLInput(type, {
          defaultProps: htmlInputProps, // <------ AND HERE, as htmlInputProps contain 'onChange' one
          overrideProps: {
            className: inputClasses,
            ref: this.handleInputRef,
          },
        })}
