ePUB version missing from zim

[Popolechien]

Most entries have an HTML and ePUB icon, and both seem clickable. The ePUB link, however, does not yield any file to download (tried both on Desktop 2.0 rc5 and macOS 2.0; zims were gutenberg_en_all_2018-10 and ale_all_2018-07.zim) - so either the scraper did not work properly, or ePubs were never meant to be included/read and therefore the logo should be removed as misleading.

This is a reader(s) issue: not supporting downloading of file. It's been reported for macOS already ; I'll let you check for desktop (might have already been fixed by now?)
