Prevent infinite reruns when no selection is made
Prevent infinite reruns when no selection is made

The way we rerun the import_js command if you are asked to make
selections would result in an infinite loop if you escaped out of the
selection list. I'm adding a guard so that reruns only happen when
there's at least one selection.
