[BUG]: crash when adding discovered feeds in dev build

[Owyn]

Brief description of the issue

I clicked discover on "https://drakescans.com/" then selected all and clicked "import" - it did nothing, so I clicked few more times - and it crashed

How to reproduce the bug?

1 add feed
2 https://drakescans.com/
3 click "discover"
4 click select all
5 click "import" - but not once but few times ( I did it cuz I felt that nothing happened after I clicked it 1st time )

• crash

What was the expected result?

no crash

What actually happened?

crash

Debug log

rssguard.log

Operating system and version

• OS: Win 10
• RSS Guard version: devbuild-cda0f79e1-lite-win10.7z

Additional info: - apparently clicking multiple times is not necessary for it to crash, it crashes anyway even if clicked ones

Fixed. The problem was that JSON document was mistakenly identified to be JSON feed while in fact it was not.
