Tested if `ChatContextProvider` is used in:
- MessageSearchProvider
- RegistrationContextProvider
- SQLiteDataHandler
- ConnectedStatusBar
- ReduxPersistGate
- gated:
- LifecycleHandler
- DisconnectedBarVisibilityHandler
- DimensionsUpdater
- ConnectivityUpdater
- ThemeHandler
- OrientationHandler
- PersistedStateGate
- Socket
and it is not. Also checked locations where we use `ChatContext`:
- native/chat/message-list-container.react.js
- native/chat/message-list-types.js
- native/chat/message-results-sceen.react.js
- native/chat/multimedia/robotext/text-message.react.js
- native/chat/sidebar-navigation.js
- native/search/message-search.react.js
- native/tooltip/tooltip.react.js
All of these files are "inside" `RootNavigator`. Only `chatMessageItemKey` from `native/chat/utils.js` is used in `chat-item-height-measurer.react.js` but this file is used in `chat-context-provider.react.js` only.
