[Bug]: <.flash /> without title crashs app at runtime

[nighthawk]

What happened?

If your .swiftui.neex file has this snippet below, it'll crash the app at runtime due to a missing title:

<.flash kind={:info} flash={@flash} />

title is optional according to core_components.swiftui.ex (which is also consistent with the same default component from core_components.ex):

attr :title, :string, default: nil

The crash is in AttributeReference.resolve which has try! even though an error is raised in this case.
