fix: Improve message retrieval with fallback after sending

[fallenleavesguy]

This pull request updates the logic for retrieving a sent message in the exports.LoadUtils function. The main change adds a fallback mechanism to ensure the message is found even if it's not immediately available in the main collection.

Message retrieval improvement:

• Enhanced the message lookup logic in Utils.js so that if the message is not found using Msg.get, it will search through chat.msgs.getModelsArray() to find the message by ID. This increases reliability when accessing newly sent messages.## Description
