No warning on corrupt export / malformed notes.

I was able to convert *most* of my notes. The output of the command was shown as:

```
Notes processed: 447

==========================
Conversion finished: 447 succeeded, 0 skipped, 0 failed. Total notes: 447
```

I processed my notes through wormi4ok/evernote2md and it stopped altogether on this one.

So it looks like I had a bad export from Evernote. I wasn't warned about this with yarle. I checked the outputDir for yarle and that note isn't in there. It is in my Evernote though, and I was able to export it individually as an enex.

I will try a full export again.
