Have a kanban arch with a field in display full in the kanban card template
```<field name="fieldName" display="full" />```
Before this commit, the class that should endup in the DOM was wrongly computed.
Technically, it was quoted in the owl template as if we passed it to a Component.
After this commit, a field having display="full" is correctly rendered.
