Webfinger: Send requests for accounts with acct: scheme
Right now, unless an LRDD template is not found, Pleroma will send webfinger requests with "account@pleroma.example" as a URI. As you can see, this is not really a URI, the proper URI would be "acct:account@pleroma.example", I suspect it was left this way due to GS compatibility, which we no longer have to have. Not sending requests with acct:
makes peertube account lookup not work, among other problems.
