Description of problem:
It is not possible to create bookmark for Global Parameters, neither via API nor UI.

API:
> Making HTTP POST request to https://sat6.com/api/v2/bookmarks with options {'verify': False, 'auth': ('admin', 'changeme'), 'headers': {'content-type': 'application/json'}} and data {"controller": "common_parameters", "query": "\u5653\u3def\uf902\ud855\udcbf\ud849\udf20\u1d9b\ud835\udc10\ud86a\udecd\ud3da\ufa11", "public": false, "name": "uZSPlCrazx"}.
> Received HTTP 422 response: {
  "error": {"id":null,"errors":{"controller":["common_parameters is not a valid controller"]},"full_messages":["Controller common_parameters is not a valid controller"]}

UI:
After clicking on `create bookmark` modal window is opened, but after clicking on submit button page redirects to `create bookmark` page and further clicking on sumbit button ha no effect.

According to production.log in this case also `common_parameters` is used as controller:
