[bugfix] Fix multiple dereferences of boosted status causing media duplication (#589)
* add some announces to test models

* start on announce test logic

* test federatingDB.Announce

* change signature of GetRemoteStatus

* remove 'refresh' logic and replace it with refetch

* go fmt

* remove timeline manager from processor test

* make zork created at determinate

* test get account statuses

* test get + serialize zork

* make account keys determinate

* make admin accountCreate time determinate

* test account to as
