Correct isset behaviour

[michaeldyrynda]

In order to be able to use ternary / Laravel Blade or syntax, provide an __isset magic method.

👍 this looks good to me and makes sense.

It would also need to return true if the property exists on the model. Sometimes you might not override a model property and you would want it to show as set.

[michaeldyrynda]

If you weren't changing the property that's on the model, wouldn't you just display that directly ($model->property rather than $model->present()->property)?

+1 ... this is also required when using presenter models in Twig templates (because Twig won't bother asking for a property or method unless it passes an isset check first)
