feat: db changes to accommodate new cross device syncing logic. (#450)

* feat: db changes to accommodate new syncing logic.

Using timestamp to sync is a bit skewed due to system clock etc and therefore there was a lot of issues with it such as removing a manga that shouldn't have been removed. Marking chapters as unread even though it was marked as a read. Hopefully by using versioning system it should eliminate those issues.

* chore: add new line.

* chore: remove isSyncing from Chapter/Manga model.

* chore: remove isSyncing leftover.

* chore: remove isSyncing.

* refactor: remove isSync guard.

Just use it directly to 1 now since we don't have the isSyncing field in Manga or Chapter.

* Lint and stuff

* Add missing ,
