When fetching a large number of personal documents, there is a chance of
receiving the following JSON structure leading to a KeyError:
```json
{"OwnershipData":{"success":false,"error":"GENERIC_ERROR"}}
```
In this case, ignore the error and continue execution.
error:
ebooks = [e for e in ebooks if e["origins"]["origin"]["type"] == "purchase"]
TypeError: list indices must be integers or slices,not str

I'm encountering a 'File name too long' issue when playing with
kindle_download_helper. This patch sets the default value of
--cut-length (from 100) to a smaller value (76).

Can we have a smarter algorithm to truncate the file name?
