  quota-clone: Move state tracking to user context

This way there's no need to do multiple flushes when e.g. multiple
mailboxes change.

The flush had to be removed from close(), because the code path recurses:

 * mailbox_transaction_commit() when mail is saved
 * quota_count() starts counting the quota, which opens and closes mailbox
 * quota_clone_mailbox_close() attempts to flush quota, which again recurses
into quota_count(), which returns 0 for the quota value.
