getDisplayName() does not seem to work

The getDisplayName() method is returning the node name, and not the hippo:name property on the handle as expected.

reproduction:

1. Create a fresh 11.1 archetype project

2. Add some content, like news

3. Call bean.getDisplayName() in the HST component (EssentialsContentComponent)

expected:

the hippo:name property on the handle (The medusa news)

observed:

the node name (the-medusa-news)
