addBlock crashes with TypeError on ReadOnlyMode

[dckc]

The real issue is:

$ rnode propose
Response: Error while creating block: ReadOnyMode

but using rchain-api, I get:

$ rclient propose -v
options: { '--help': false,
  '--host': 'localhost',
  '--port': '40401',
  '--verbose': true,
  RHOLANG: null,
  deploy: false,
  propose: true }

@JoshOrndorff is unable to reproduce

he started a node without casper (rnode run -s -n) and tried to deploy (by running node rhopm.js --package exampleProject/powers.rho)

It failed with a reasonable diagnostic:

(node:6644) UnhandledPromiseRejectionWarning: Error: Error while creating block: ReadOnyMode
    at responseP.then (/home/joshy/ProgrammingProjects/rhopm/node_modules/rchain-api/rnodeAPI.js:156:38)

version: It's the same rhopm that's the tip of master on my github and rchain-api 0.7.1-beta.2

Was this actually using addBlock or was it createBlock? I believe createBlock is the equivalent service of rnode propose.
