feat(ui/modules/Linphone/Chat/IncomingMessage): display avatar only for the first incoming message of a sequence

fix(ui/modules/Linphone/Chat/Chat): add a workaround to this issue: https://bugreports.qt.io/browse/QTBUG-49989

  - use `asStringUriOnly` instead of `asString` to parse calls in `SipAddressesModel`
  - `Contact` component uses only a `SipAddress` object now

fix(src/components/smart-search-bar/SmartSearchBarModel): use contact (if exists) username on search

  - rename `Database` class to `Paths`
  - use linphone logger
  - better log format when the app is compiled in debug mode
  - use the log collection of linphone

  - supports message received notification
  - provide a way to test app focus

  - supports linphone cbs
  - handle received messages
  - `SipAddressesModel` refactoring

fix(ui/modules/Linphone/Contact/Contact): do not display presence if contact is not registered in app

  - remove `SelectContact` component
  - remove `NewCall` view
  - fix styles & coding style if views

  - it uses a style file
  - provide signals handlers
