Listen to a sent confirmation for all message types

[hesterbruikman]

Problem

When adding a reaction in an offline state, it is instantly visible for user A. However, the reaction is not send when offline, nor when User A comes back online. User B never sees the reaction, while it remains visible for user A

Expected

Three options (ideally a combination of 1&2):

1. User A can add a reaction when offline, when the client comes back online, the reaction is send
2. User A can add a reaction when offline, user is informed the reaction was not send and can Tap to try again, upon which this message will disappear as soon as the reaction is send successfully
3. User A cannot send a reaction when offline

Current

User A can add a reaction when offline. User A is not informed the reaction is not send. Reaction is not send when user A comes online

Implementation

Acceptance Criteria

Reaction is successfully sent or user is informed if message is not successfully sent
or
User cannot add reaction when offline

Notes

Future Steps

Let's try to make the first option work since imo it's superior to other alternatives

User A can add a reaction when offline, when the client comes back online, the reaction is send

From conversation with @Ferossgp this is actually related to how we get and show a send confirmation for all message types.

Hiding (disallowing) reactions in offline state is not sufficient. Also with low or interrupted connections, we cannot confirm the message was send; however the client might still show as online and allow reactions.

A better solution would be to listen to a send confirmation
