Before this commit, new model term translations cannot be saved if it has been
translated before.
The reason is while translating fr_FR
the backend needs the mapping {old_term_fr: new_term_fr} to update old_value_fr
However the UI sent {old_term_en: new_term_fr} which was wrong
This commit fixes the bug by changing the key of the mapping from the
old_term_en to the old_term_fr
