Download chapter naming bug when switching chapter

[Sapo84]

The download system uses the current chapter for naming the file

This is not correct because there's no guarantee that is same chapter that was downloaded, in fact if you click on download and switch chapter immediately the chapter download is the previous one but the name refers to the current one.
It would be better to save the name of the chapter being downloaded in the local function of the Download manager and pass it as an argument to initiateDownload function, that way would keep the correct name even if the chapter is changed in the UI.

Wait that's hilarious. I should have actually reviewed the download feature pull request, will fix soon

Apologies for being so late.
This was actually fixed with 8185ab7 but wasn't deployed until recently due to unforeseen circumstances. I'll leave this issue open for a while in case something goes awry.
