Update production yarn deps

What does this MR do?

Production deployed to replace homepage failed because upath specifies it needs node <=9 (and we have v10.6.0). A yarn upgrade means we use a patch version higher which relaxes the restraint.

  The command "cd ~/production-deploy/releases/13 && (cd client && yarn && ya  
  rn build)" failed.

How confident are you it won't break things if deployed?

Well, it upgrades all the npm deps (within range), but if the test pass, should be ok :)
