nesting anyOf under allOf is broken

I can't get this to work:

let v = themis.validator({
    id: 'test',
    allOf: [
      {
        anyOf: [
          {
            required: ['test']
          }
        ]
      }
    ]
});

let report = v({
    test: 2
}, 'test'); // gives report.valid = false

Works fine in other JSON validators... ironic since you're actually using this pattern in the feature to validate schemas... which is inherently broken as a result.. e.g. force_additional: true doesn't work in options.

However, the big issue here is probably that validation is broken...
