Moved all avatar related work to AvatarService

- fetchAvatar, fetchAvatarPep, fetchAvatarVcard, checkForAvatar moved from XmppConnectionService to AvatarService
- Several unused imports removed
- XmppSendUtil introduced to enable presencePacket and iqPacket sending without using XmppConnectionService since the account has everything needed
- UiUpdateHelper introduced to enable UI updates without using XmppConnectionService directly
