    Fixed ontology for old Evolution support and detecting folders.db
    
    The file folders.db will be in the account's cache dir when a more
    recent version of Evolution has upgraded an old Evolution mail cache. In
    that case we want to ignore the summary files, and instead rely on the
    push module
