setting up Babylone protocol

[frankhillard]

Hello,
I'm trying to activate the "babylone" protocol while using the starter-kit. Naively, I was expecting to modify the starter-kit scripts and get a running node on babylone.

Steps to reproduce the behavior:

1. add a new command in package.json
   '''
   "activate-proto-babylone": "./activate_proto_babylone.sh",
   '''
2. create a new "activate_proto_babylone.sh" (with the babylone protocol hash)
   '''
   #!/bin/bash
   ./node_modules/.bin/granary client - import secret key activator unencrypted:edsk31vznjHSSpGExDMHYASz45VZqXN4DPxvsa4hAyY8dHM28cZzp6 --force
   ./node_modules/.bin/granary client - activate protocol PsBABY5HQTSkA4297zNHfsZNKtxULfL18y95qb3m53QJiXGmrbU with fitness 1 and key activator and parameters $PWD/protocol_parameters_babylone.json --timestamp $(TZ='AAA+1' date +%FT%TZ)
   ./node_modules/.bin/granary client - import secret key "bootstrap1" "unencrypted:edsk3gUfUPyBSfrS9CCgmCiQsTCHGkviBDusMxDJstFtojtc1zcpsh"
   ./node_modules/.bin/granary client - bake for bootstrap1
   ./node_modules/.bin/granary client - rpc get /chains/main/blocks/head
   '''
3. create a new 'protocol_parameters_babylone.json'
   '''

   "initial_endorsers": 24,
   "delay_per_missing_endorsement": "8"
   }
   '''
4. npm run init
5. npm run start
6. in a new terminal, npm run activate-proto-babylone

I was expecting a running node in babylone

The script start (import secret key activator seems to work) and then "activate protocol" command fail/freeze ...
