send from stdin seems to be broken

[sidhussmann]

Sending a message via stdin seems to be broken in version 0.13.7:

echo "hello world" | signal-cli send +XXX
INFO  AccountHelper - The Signal protocol expects that incoming messages are regularly received.
Sending empty message is not allowed, either a message, attachment or sticker must be given.

While the -m option still works:

signal-cli send +XXX -m "hello world"
INFO  AccountHelper - The Signal protocol expects that incoming messages are regularly received.

I tried with the following installation methods:

• nix-env -i signal-cli
• https://flathub.org/apps/org.asamk.SignalCli
• https://packaging.gitlab.io/signal-cli/installation/standalone/
