fix: Fix loading following messages condition WPB-9465

[svitovyda]

WPB-9465 [web] Conversation scrolling stops loading following messages

Description

This fixes the part of the problem. TODO: If messages are all read, the scrolling will trigger the next messages loading. But if the messages (30+ missed calls and some content messages after them) are not read, the scroll to the last message will not trigger the loading, new sent messages will appear, but the missed messages will not be shown TODO: in most cases

const lastMessage = conversation.getNewestMessage();
if (!isLastReceivedMessage(lastMessage, conversation))

can be replaced with !conversation.hasLastReceivedMessageLoaded(), I'd do this refactoring within this fix too.

Also, the isLastReceivedMessage can be a public method of conversation
