4ef64ad Realized the playstate is not synced with UI when the application is resumed after being killed either in the app switcher by the user or in the background. This means the service tracking/syncronizing progress isn't updated either and the UI doesn't have an active player. With this change the playstate is synced when the app is resumed and the ui service is ready.
f047218 Added playback sync state to more places and added a fallback to last server session if no local session is found.

In-depth Description

Realized the playstate is not synced with UI when the application is resumed after being killed either in the app switcher by the user or in the background. This means the service tracking/syncronizing progress isn't updated either and the UI doesn't have an active player. With this change the playstate is synced when the app is resumed and the ui service is ready.

How have you tested this?

Running on phone and emulator. Play a book swipe to close audiobookshelf in recents. Open audiobookshelf and player opens with the correct book and play state. Without these changes the ui and services were un-aware of the current play state. Tested in multiple states closing and opening the app. Still testing with previous pr to make sure it solves android auto and syncing issues.

Update: tested throughout the day and not seeing any increased battery usage. Still working great and listening sessions are being recorded in server.
