ApiQueryContentTranslation should check if there is a saved data for the given translation id in cxc_corpora table. If so access the data from there , aggregate the sections in their linear order and return it.
If the data is not present in corpora table, check that in drafts table and fetch it.
We will require some changes in section restore logic to accommodate this data. we can try to send the data as close to what we would send from drafts table
