#2857 attempt to reapply fix for dropdown

@sfmskywalker trying to reapply the fix for dropdown as in #2857.

Simply I'm trying to reassign the value at the end of componentWillLoad() to force the default value.

if (this.currentValue != undefined) {
      this.propertyModel.expressions[defaultSyntax] = this.currentValue;
    }

This needs to be validated with the cascading dropdown feature from @jdevillard

The fix seems to work correctly on the cascading dropdown 👍, however, it seems to have an other issue on the first load.

The value of the third dropdown is undefined :

because the call to the api is done with only one dependand value instead of the two :

color depends on Brand and Model and only Model is set at the init.

If we change one dropdown, all the events/call are set correctly. It's only at init.
