Description of the bug:

sed is applied only once by line:
original archive:
import [COMPONENTNAME]Base from './[COMPONENTNAME]Base';
const [COMPONENTNAME] = styled( [COMPONENTNAME]Base );
export default [COMPONENTNAME];

after execute:
shell.sed( '-i', \[${"componentname".toUpperCase()}\], "AUITest", "component.js" );`

Result:
import AUITestBase from './[COMPONENTNAME]Base';
const AUITest = styled( [COMPONENTNAME]Base );
export default AUITest;
