Merge recipe notifications against the restored force (#1182)

The instance works out the recipe notification delta against the cleared
list the player had when the download started, but the save applied it
after the download restored player.force. A player whose force changed
kept notifications they had cleared elsewhere, and recipes only the old
force had dropped out of the failed list and were lost on the next
upload.

The download record now keeps the cleared list it sent. The save rebuilds
the stored list from it and the delta, then merges that against the
force the player has once the data is applied, as it did before #997.
Nothing extra goes over RCON.
