PieFed and Mbin take reports from the reporter too

Both speak Lemmy's shapes and joined the servers that get reports in that shape only once the pasture showed each keeps
one with its reason. By their source, PieFed dropped the instance actor's report (it makes a user only of a Person or a
Service) and Mbin kept it without the persona's words (it reads the reason from `summary` alone). With them in
`ServiceReportTakers`, each keeps the reports of a thread and of a comment from "Reports from privapub.test" with
alice's words, and none names her (piefed.sh and mbin.sh, 65 checks with the full sweep's 876). A report of a PieFed
account alone, which PieFed would take from the reporter, is not sent yet; INTEROP says so.
