Description:
Asset publisher is displaying wrong order after partial or no translation of web content fields.

Steps to reproduce:

1. Use English as default language then go to Control Panel ->  Content & Data -> Web Content -> Structures 
2. Create a new structure that has one HTML field and another Number field 
3. Go to Web content tab and create from the previous created structure three new web contents 
4. Create a first content in the default language (en_US) with these values:
   1. Number: 1
   2. Text: Hello 1
   3. Spanish translation, with the same title, number, and the text will be "Hola 1".
5. Create a second content in the default language (en_US) with these values:
   1. Number: 2
   2. Text: Hello 2
   3. We don't add any translation here.
6. Create a third content in the default language (en_US) with these values:
   1. Number: 3
   2. Text: Hello 3
   3. Spanish translation, with the same title, number, and the text will be "Hola 3".
7. We deploy a widget Asset Publisher on our welcome page and configure it to show only the contents of that structure: Asset Publisher -> Configuration -> Setup -> Asset Selection -> Asset Type: Web Content Article -> Web Content Article Structures: select the structure created in point 2.
8. Configure Asset Publisher to sort by "number" field: Configuration -> Ordering -> Order by: number. 

 Expected behavior
The order should be maintained if language is changed and translation exists.

 Actual behavior: 

• We display the page in the default language, English => The order is: 3, 2, 1.
• We display the page in Spanish (translation available for field 3 and 1)=> The order is 3, 1, 2.
• We display the page in French (no translation available) => The order is 1, 2, 3.
