Problem/Motivation
Translated content appears on the original content when an original field was left blank, but then content is added for the translation.
Steps to reproduce:
1. Enable Content Translation and Language modules.
2. Add a new language to the site.
3. Edit translation settings to enable translation on Basic Page content type and body field.
4. Add a new text field "Test translatable field" and set it to be translatable.
5. Create a new page in English, adding body content, but leaving the test text field blank.
6. Add a translation for the page, translating body field, and *add content* in the test text field.
7. View the page in the new language, confirming that the translated page shows.
8. View the page in the original language, noting that the translated content appears for the test-field (instead of no content).
Expected behavior:
When viewing the original node, I would expect that NO CONTENT would be visible when viewing the node in the original language.
