fix to load conversationlist only once after login

without this fix:
after login the conversation list opened multiple times for the same user when other users already exist

reason:
proceedWithLogin() in AccountVerificationController is called multiple times because for ALL accounts (for (User user : userEntityObjectList)) the workers send their results via eventBus to

AccountVerificationController#onMessageEvent(eventStatus: EventStatus)

So depending on how many accounts exist, the ConversationList was loaded x times.

solution:
if internalAccountId is already the active one, no need to load the conversationList another time.

when there is only one account -> currentUser id and internalAccountId are the same so it would not enter the condition. Thus also allowing it when only one user exists.
