feat: background sync even if interval not passed

this avoids the scenario of:
1. study some cards
2. leave the app within a time less than 10 minutes (so autosync isn't triggered)
3. open the app again and have the wait the studied cards in `1.` to be synced, although they could have been already synced in the background
