Comment 3 for bug 1588645

I just checked in Click Index to make sure the Department translations have been imported there, and they have:

```
curl 'https://search.apps.ubuntu.com/api/v1' -H 'X-Ubuntu-Architecture: armhf' -H 'Accept-Language: zh-CN' | jq -C .
{
  "_embedded": {
    "clickindex:department": [
      {
        "has_children": false,
        "_links": {
          "self": {
            "href": "https://search.apps.ubuntu.com/api/v1/departments/social-networking"
          }
        },
        "name": "社交网络",
        "slug": "social-networking"
      },
      {
        "has_children": false,
        "_links": {
          "self": {
            "href": "https://search.apps.ubuntu.com/api/v1/departments/travel-local"
          }
        },
        "name": "旅游与本地",
        "slug": "travel-local"
      },
      ...
```
