Telepathy Ring Hardcode in SFOS components

• commhistory-daemon
  • accountpresenceservice.cpp
    if (account->cmName() != QLatin1String("ring")) presenceUpdate(account, presence); Probably we should check StorageRestrictions (not exposed in TpQt API) instead of cmName, see Wire up Account .Storage properties telepathy-qt#34.
  • mmshandler.cpp, smartmessaging.cpp: refs to ringAccountPath, such as event.setRecipients(ringAccountPath)
• libcommhistory
  • commhistory-tool.cpp if (isSms) { localUid = RING_ACCOUNT; }
  • declarativegroupmanager.cpp localUid.indexOf("/ring/tel/") >= 0 ? SMSEvent : IMEvent
• sailfish-components-contacts-qt5
  • ContactActivityList.qml isPhone: localUid.indexOf('/ring/tel/') >= 0
  • RecentContactsList.qml isPhone: localUid.indexOf('/ring/tel/') >= 0
• jolla-messages
  • A lot of references to telepathyAccounts.ringAccountPath
• voicecall
  • TelepathyProvider uses deprecated Calls API (not implemented in telepathy-ofono). Option: implement a new/old API fallback in TelepathyQt.
  • TelepathyProvider/shouldForceReconnect()
