EntriesExport/epub: replace epub identifier with unique urn
We replace the title used as the unique identifier of the epub file with a urn following the format: urn:wallabag:{sha1("wallabagUrl:listOfEntryIdsSeparatedByComma")} This format is repeatable: it always gives the same uid for the same list of entries. Fixes #3811 Signed-off-by: Kevin Decherf <kevin@kdecherf.com>
