Passing content (slot/children) to a component without slot breaks

[kaisermann]

REPL

The following component throws a Cannot read property 'default' of undefined:

App.html

<Test>Hmmm</Test>

<script>
	export default {
		components: {
			Test: './test.html'
		}
	}
</script>

Test.html

<div>
	I don't have a slot
</div>

Ah, yep. I think this should probably throw a more helpful error in dev mode:

<Test> cannot have children as it does not have a <slot> element

With that change, the current prod mode behaviour is probably acceptable?

I wonder if there's a smart way to construct a stack so that when you click the trace, it points to the correct line in the source code.

This doesn't throw an error anymore. Maybe there should be a warning along the lines of <Test> does not have a <slot> element?
