babel-polyfill replaces existing Promise implementation

[adrian-gierakowski]

same as: feathersjs/feathers#510

it is very well described in the above issue so I will not repeat it here ( it would suffice to copy and paste replacing feathers with civic-sip-api )

for others needing a workaround util this is resolved, replace:

global.Promise = require("bluebird")

with

Object.defineProperty(global, "Promise", {
  value:require("bluebird"),
  writable:false
})

@adrian-gierakowski Thanks for giving the background here. Busy looking into it.

Updated to use babel-runtime to stop polluting globals.
