Message cooldown not in sync with the BE in certain cases

[MarinTolic]

Context & proposal

Steps to reproduce:

1. Find a channel with a cooldown period
2. Send a message with an attachment
3. Reply to the message immediately after the cooldown ends

Result:

Message fails to send in both apps with the following printed out in the logs in UI Components:

E/Chat:MessageInputViewModel: Could not send message with cid: messaging:6da0a78b-8880-44cc-867b-9d9a448c80aa. Error message: Status code: 403, with stream code: 60, description: SendMessage failed with error: "user jc is not allowed to send messages on channel messaging:6da0a78b-8880-44cc-867b-9d9a448c80aa under cool down period(10s)". Cause message: null

Acceptance criteria

To accept this task we need to complete the following items:

• [ ] Locate the issue and sync with the BE team if needed.
• [ ] Fix the issue.

Also, some user roles should be able to bypass the cooldown (e.g. admins). I suppose there should be a channel capability for that.
