Updated react sample scripts

[ndsnas]

Fixed package.json script -> start:connected-ssr

Description

"start:connected-ssr": "scjss-verify-setup && npm-run-all --serial bootstrap:connected --parallel start:react start:watch-components start:http-renderer"
start:http-renderer: doesn't exist in scripts
it should be start:http-renderer-holygrail

Motivation

jss start:connected-ssr gives error as it can't find start:http-renderer in scripts.

How Has This Been Tested?

tested by running jss start:connected-ssr. It ran successfully start:react and holygrail in parallel.
