    Bug 764172 - [IMAPx] Load folder summary into memory before sync/fetch
    
    Make sure the folder summary message infos are loaded in memory before
    folder content fetch (refresh) and before the synchronization (store
    local changes), to avoid slowness when reading message infos one by one.
