[fix] missing border on group shape when unlocked (#2075)

This PR fixes a bug where the indicator on a locked group (or any
shape!) would not appear when the shape was unlocked. This happens
because the `memo` equality checker filtered out changes to the shape's
locked property if they did not effect any other properties.
