[FIX] : Filtered out self messages from AI reply generation

[not-meet]

Issue(#40)

Closes #40

Acceptance Criteria fulfillment

• AI modal should take the last message of the other user
• User receives a error notification when no valid messages are found to generate AI response

What changes i made ?

• I changed the logic from poping the last message to finding the last message form a distinct user
• I also added a notification in all the languages to notify the user if there are no user message in the room

POC -
