Title: Fix update card

#5142 introduced a bug caused by duplicating the class `js-membership-card-lastfour`, thus the wrong span was updated when a user changes their card. Somewhere down the line the update animation also stopped working because the CSS rule had the wrong selector. This pull request fixes both of those issues.
