docker: downgrade alpine to 3.13 again

See https://wiki.alpinelinux.org/wiki/Release_Notes_for_Alpine_3.14.0#faccessat2 ;
this maintains compatibility with older, buggy versions of docker and runc.
Alpine 3.13 is supported until 2022-11-01.

CHATHISTORY with nonexistent msgid should send empty batch

fix case where CS TRANSFER as an operator required acceptance

It was sending MESSAGE_ERROR, which was inappropriate. Send an empty batch
for now (this is at parity with the in-memory implementation).

Reported by @mogad0n. If a user had both operator privileges and
channel owner privileges, the CS TRANSFER would proceed as though
unprivileged, requiring acceptance by the receiving user. Fix this
to not require acceptance.
