@WithAttributes should allow its use on Constructor injections

When creating a Command, you can specify the attributes of a UI field by using @WithAttributes and @Inject:

@Inject
@WithAttributes(label = "Version")
private UIInput<String> version;

The problem is we can't use this approach with constructor injection because @WithAttributes is not allowed on parameters.

PS: This is easily avoided by instantiating UI inputs using the initializeUI method.
