EntriesExport/epub: replace epub identifier with unique urn

Browse Source 
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
