docs: mismatch between Angular version in embedded examples and plnkr examples on master

[Narretz]

See http://stackoverflow.com/questions/40043549/ng-switch-when-separator-not-working-in-angularjs/40044632#40044632

Maybe this should be fixed in dgeni-packages/examples.

The plnkr opener requests the manifest.json, which contains the files that should appear in the plnkr. And the files are generated by dgeni based on the deployments. So maybe we need an extra plnkr deployment?

Fix was wrong, reopening
