Unable to send reaction

[Sup3Legacy]

On both the current master branch, the reaction feature seems to be broken.

When sending a reaction, it correctly appears locally but seem not to get sent as it does not appear on any other device.

After experimenting a bit with the code, it seems that adding

timestamp: Some(timestamp),

in the message

gurk-rs/src/signal.rs

Lines 168 to 176 in eda8557

	let mut data_message = DataMessage {
	reaction: Some(Reaction {
	emoji: Some(emoji.clone()),
	remove: Some(remove),
	target_author_uuid: Some(target_author_uuid.to_string()),
	target_sent_timestamp: Some(target_sent_timestamp),
	}),
	..Default::default()
	};

solves the issue.

After some more testing, it appears this problems occurs whenever I'm connected to an unstable network.

This raises another question : we currently do not support sending/caching messages when no connection is available. Would it be possible to implement this?
