Fix creating a directory in the Save-as dialog.

This regression was caused since we were listening for commands on the dialog container only. In the save-as dialog, the new folder button is on the footer, which is not a child of the dialog container. This patch adds listening for the command on the footer.

TEST=Tested manually.
