Impossible to import per language

[indigoxela]

Things to verify: is "translation" the right key for all entity types? My assumption is based on:

• https://github.com/backdrop/backdrop/blob/1.x/core/modules/entity/entity.api.php#L130
• https://github.com/backdrop/backdrop/blob/1.x/core/modules/entity/entity.module#L348

With #123 applied I got the language aware import working with nodes. We need to test taxonomy terms, too.

Testing is a bit complex. My setup might give some hints:

• On another site I created a view to export a feed of (translatable) nodes
• The same nodes I wanted to import in a Backdrop site (but the langcode should be kept)

The settings (roughly):

• Attached to: none
• Periodic import: off
• Import on submission
• HTTP Fetcher
• Download content from a URL.
• Common syndication parser
• Parse RSS and Atom feeds.
• Node processor
• Create and update nodes.

There's no way to set a "dynamic" language with RSS (same as in Drupal IIRC), so I created two importers - one for each language.

Now that I've merged your PR to get tests running they're running on this one. As expected many still don't work but shouldn't stop this one from being merged. (I won't be able to look more closely for a couple weeks so someone else could)

It looks pretty legit. translation is always assigned in https://github.com/backdrop/backdrop/blob/1.x/core/modules/entity/entity.module#L348.
