Sending message to group issue

[eugenyuk]

Hi,

For some reason I've strarted to encountered with the following problem when send a message to a group: the message was sent and I see it reached the group, but signal-cli shows the following:

$ echo 'Test message' | signal-cli-native --config /home/.local/share/signal-cli -v --scrub-log -a +123456789012 send --message-from-stdin -g ***
