When a `we-select` has no elements, it is drawn as a flat line.
This commit puts a "/" in its toggler content. This character is the
same one as the one that is displayed if the selected value is not one
of the available values.
Steps to reproduce:
- Delete all `website.snippet.filter`
- In debug mode, drop a "Dynamic Snippet" in a website page
- Select it
=> The "Filter" option was displayed as a flat line.
