Steps to reproduce

1. Go to Demo and open Pages-app
2. Create/edit a page
3. Create a component which doesn't have a link (as HTML, textAndImage, Image...)
4. Click on the component and choose "Change template"
5. Select "Link" or "Teaser"
6. Check the layout breaks and no default option (page, external, download) are selected
7. Once you fulfill the required fields, the error disappear 

Expected results

The Link/Teaser component behaves as when you create a new component instead of changing the template. It must:

1. Select by default the "Page" option within the Link Type field
2. Not break the UI

Actual results

The opposite mentioned above
