Title: WebSearch: collection tree score as in next.

* Updates how the `score` value from `collection_collection` is used
adopting next way, the lower the score the higher the position.

* Provides an upgrade recipe to update the `collection_collection`
relationships. It changes the score setting its value from 0 to the
number of "son collections".
