Translations create multuple posts for the main language if the post type is not translatable

[villesiltala]

If the importer data holds translation data for Polylang, the import process creates a multiple posts under the main language if the post type is not translatable. This will happen as many times as there are translations defined for the post.

The save process should discard translations for post types not set to be translated with Polylang and throw an error. This would prevent creation of multiple posts and would give the user information about translations not being active for the post type.
