Reports - Improvements on message tracking

[juancp-contidosdixitais]

Currently, tracking messages from the user report would only indicate cases when the user receives a message, not when the user sends a message, since it is assumed by default that a sent message will be answered, but this is not always the case. If we want to fully track, we must include those sent messages.

We created a new method (getMessageExchangeWithUser) in main/inc/lib/message.lib.php to obtain both the users from whom they have received messages and to whom they have sent messages and we modified the loading of this data in main/mySpace/myStudents.php.

On the other hand, a bug was identified where the message load is duplicated:

	if ($filterMessages) {
	$users = MessageManager::getUsersThatHadConversationWithUser($student_id, $coachAccessStartDate, $coachAccessEndDate);
	} else {
	$users = MessageManager::getUsersThatHadConversationWithUser($student_id);
	}
	$users = MessageManager::getUsersThatHadConversationWithUser($student_id);
