FIX: send notifications after a chat message was updated with new mentions (#21173)

Browse Source 
Steps to reproduce the bug:
1. Send a chat message
2. Edit the message and add a mention to it
3. The mentioned user won't receive a notification

This PR fixes the problem.

Also:
1. There's no need anymore to have a code for removing notifications in the `notify_edit` method, because a call to `@chat_message.update_mentions` in the first line of the `notify_edit` method does that job:
    ff56f403a2/plugins/chat/lib/chat/notifier.rb (L90)

2. There's no need to load mention records from database, it's enough to pluck user ids
