* add migration to clean up duplicated media

* use /tmp/gotosocial for testrig storage path

* defer remove storage tempdir

* skip if not attached to status or status not found

* log errors at error level

* only log delete as else clause if successful

* just return nil on down

* reword delete logic a little bit

* check if storage base path is defined

* check for status id more thoroughly

* don't log error if just no rows

* go fmt

* break statusIDLoop when found

* break currentlyUsedLoop when found
