Fix disabling autofill in last versions of Chrome

Last versions of Google Chrome ignore property 'autocomplete="off"'. We need change it to 'autocomplete="new-password"' for disabling internal
Chrome autofill feature when plugin initialized. It works for any text fields, not only for password text fields.

Change
            // Remove autocomplete attribute to prevent native suggestions:
            that.element.setAttribute('autocomplete', 'off');
to:
            // Remove autocomplete attribute to prevent native suggestions:
            that.element.setAttribute('autocomplete', 'new-password');
