FIX: Further optimize mentioning groups in chat messages (part 2) (#24185) 
This is a follow-up to e6299a3. I additionally fixed these three things:

1. Since e6299a3 there's no need anymore to join the group_users table 
when looking for users who were reached by a group mention, so 
I removed that join in that commit. But turned out we were joining 
the group_users table twice, so I removed the second join in this PR. 
That drastically speeded up my test query, from 6 sec to 0.26 sec.
2. We also were joining twice the user_chat_channel_memebership table, 
so I removed the second unnecessary join too.
3. We actually need to join the user_chat_channel_memebership table 
only in certain cases, and we don't need to do that for group mentions, 
so I fixed that too.

As a result of these changes, time of my test query fall down from 
6 sec to 0.001 sec. And the resulting SQL query now contains only 
one JOIN statement.
