Monica kept a vCard's raw ORG as company text, the trailing semicolon too;
escaped as text it joined the name, so the composer trims it before it's through.
A company that was only a semicolon now writes no ORG line at all,
the same blank Monica's own migration made of it, nulling ";" for good and all.
