Followup to Use a Branding Block cache fix - 2005546

Problem/Motivation

Re: A comment from @Wim Leers after #2005546: Use branding block in place of page template branding variables (site name, slogan, site logo) went in:

"This line sadly means that any D8 site that already existed will get a branding block (yay!) that is marked to not ever be cached (boo!).

This line simply does not belong here. So… it looks like we need a new update function that takes the site branding block and removes this setting"

Proposed resolution

Remove the offending line.
