    Fix preserving of non-UI tag fields
    
    After refactoring of some of the tag copying functions in
    9aad89da3bbe7c822eb12fb082e7d4a085eb3ed6, "other" tag fields (those not
    shown in the UI, but intended to be preserved) were lost when saving a
    file with modified tags. There was one instance in the refactoring where
    arguments to et_file_tag_copy_other_into() should have been swapped, and
    were not.
    
    Thanks to Philippe Troin for the bug report and initial patch.
