workspaceThumbnail: Update visibility when showing the overview

There's currently a bug that we continue showing the workspace minimap
when the number of workspaces changes back to 1 during the session (ie.
outside the overview). Fix that by also updating the workspaceThumbnails
visibility when entering the overview.
