Title: Correctly display enums consisting of arrays in the show page

The show page displays correctly enums when they are hashes or arrays of arrays, but it incorrectly displays enums consisting simply of arrays, such as:
```ruby
['value', 'other_value']
```

This is the form used in Rails enums. This patch correctly displays such enums.
