fix: Conversation scrolling stops loading following messages

[przemvs]

https://wearezeta.atlassian.net/browse/WPB-9465

Description

Probably something was wrong while refactoring. Previously we not checking all messages, probably this if checking will fix this issue.

Previously code:

readonly loadFollowingMessages = () => {
    const lastMessage = this.conversation().getLastMessage();

    if (lastMessage) {
      if (!this.isLastReceivedMessage(lastMessage, this.conversation())) {
        // if the last loaded message is not the last of the conversation, we load the subsequent messages
        this.conversationRepository.getSubsequentMessages(this.conversation(), lastMessage as ContentMessage);
      }
    }
  };
