graby will throw an Exception in some case (like a bad url, a restricted url or a secured pdf).
Import doesn't handle that case and break the whole import.
With that commit the import isn't stopped but the entry is just skipped.
Also, as a bonus, I've added extra test on WallabagImportV2 when the json is empty.
- convert english translation to translate key
- remove baggy template for login (never used since user isn't logged in and it'll use the default theme: material)
- fix tests about text in response (now checking translation key instead of translated text)
- remove all ugly `<div class="hidden">{{ form_rest(form) }}</div>`
- list services in /import
- add url to import service
- ImportBundle routing are now prefixed by /import
- optimize flush in each import (flushing each 20 contents)
- improve design of each import
- add more tests
For the moment, we won't do a queue system, just a plain synchronous import.
We also use ContentProxy to grab content for each article from Pocket.
Error from Pocket are now logged using the logger.
The ImportInterface need to be simple and not related to oAuth (not all import will use that method).
