Bug 496274

SUMMARY
Feed entries not added to database if all the parameters of the feed entries aren't passed

STEPS TO REPRODUCE
1. Add my [feed](https://soumyadghosh.github.io/website/index.xml) in the app
2. Refresh the feed
3. See the error

OBSERVED RESULT
```bash

```

And none of these got added

EXPECTED RESULT
It should've made some default values and added the entries in the database
