Config does not validate required nested attributes

[p2kmgcl]

When using Config.arrayOf(...) and Config.shapeOf(...) it does not check nested attributes inside them, for example, for this rule:

Config.arrayOf(
	Config.shapeOf({
		a: Config.string().required()
	})
)

Metal say's these are valid:

• []
• [{ a: '' }]

But also this, which shouldn't be:

• [{}]

How ever, it does throw an error for:

• [{ a: 1 }]
