Fixed wrong deletion logic from the DB

[TSlashDreamy]

user_1, user_2

{
  "_id": {
    "$oid": "65568c34d556695822907892"
  },
  "text": "Hi!",
  "clearedFor": [user_1],
}

Previously:
user_1 could delete the message entirely from DB even if he is in clearedFor field (user_2 could do this too)

Now:
Only user_2 can delete the message entirely from DB (we need to have user_1 in clearedFor field for this)
