New version issues

[NLZ]

I tried to download title id 1 (Tower of God) which I already had downloaded with older versions. Now it threw this error:

Traceback (most recent call last):

KeyError: 'manga_id'

After deleting the old 1_data.json file the download worked, so I assume the issue is that there is no logic to handle the old json (discard/migrate).

But then another issue popped up that it started to redownload everything under a new name, for example Tower of God - d110 (v02) [The Company].cbz, emphasis on d110, instead of c110.

Downloading chapter 52309 (v02c110) directly only checks that the file (c110) already exists, so only if I do the title download that it decides to save it under a different name.

So I guess something funky is going on here, but I'm too tired to debug tonight: https://github.com/Rudoal/mdownloader/blob/017091e3b820148540fd6d46cd5e34e05f8252ae/components/exporter.py#L57

The second issue is working as intended, as this series has overlapping chapter numbers which will mess up the order of the downloaded chapters. I'll look at the other issue in the morning.
