Ben Gotow 26fe05153c feat(offline-status): Show a bar when not connected to the API
Summary:
The TaskQueue does it's own throttling and has it's own processQueue retry timeout, no need for longPollConnected

Remove dead code (OfflineError)

Rename long connection state to status so we don't ask for `state.state`

Remove long poll actions related to online/offline in favor of exposing connection state through NylasSyncStatusStore

Consoliate notifications and account-error-heaer into a single package and organize files into sidebar vs. header.

Update the DeveloperBarStore to query the sync status store for long poll statuses

Test Plan: All existing tests pass
