  imapc-quota: Avoid sending unnecessarily many GETQUOTA[ROOT] commands

The last_refresh == ioloop_timeval check didn't work, because the refresh
itself updated ioloop_timeval. This caused a single quota lookup to issue
multiple GETQUOTA[ROOT] commands to imapc.

  lib-storage: Avoid unnecessary UIDNEXT lookups after saving a mail

The vsize checking code was expecting that this would always be a cheap
operation, but with imapc code it could trigger a remote STATUS (UIDNEXT)
call. Do this only when we've checked that this mailbox is updating vsize
header at all.
