Force sync of snoozed mailbox

[JohannesGGE]

Is your feature request related to a problem? Please describe.

If the snooze mailbox is not synchronized in the background, the wake job might not see moved messages and therefore doesn't move the messages back to the INBOX.

Describe the solution you'd like

To be able to move messages back to their original mailbox on time, the "Snoozed" mailbox needs to be synced frequently.
