    [IMAPx] Speed-up folder cache removal on folder sync
    
    This used to save store's summary after each single folder removal,
    which includes also an fsync() call. Just remove unknown folders and
    save changes once significantly speeds-up the initial folder hierarchy
    sync with many folder removals.
