    EServerSideSource: Don't write changes to disk until exported.
    
    If a collection backend is configuring an EServerSideSource from a
    worker thread, avoid writing changes to disk prematurely.
    
    Explicitly calling e_source_write_sync() still works as advertised
    whether the source is exported or not.
