Wrong loading with autoStack in a module

When we make a new module, depending on duniter and calling duniter.statics.autoStack(), the stack tries to find the modules in node_modules/duniter/package.json instead of local package.json.

This behavior could be fixed by adding a 2nd parameter to autoStack(), giving the directory where to look at:

autoStack: (priorityModules, dir) => { 
  const pjson = require(path.join(dir || __dirname, './package.json')); 
  // [...]
}

And on the call side:

const stack = require('duniter').statics.autoStack([{
  name: 'duniter-hello',
  required: require('./index')
}], __dirname)

Or with #989 (closed):

require('duniter').statics.quickRun(__dirname, './index.js')

There is a more elegant solution: https://stackoverflow.com/questions/8131344/what-is-the-difference-between-dirname-and-in-node-js

We do not need to give __dirname from call site, duniter can already know it with path.resolve('.').

So finally the code would be:

autoStack: (priorityModules) => { 
  const pjson = require(path.resolve('./package.json')); 
  // [...]
}

const stack = require('duniter').statics.autoStack([{
  name: 'duniter-hello',
  required: require('./index')
}])

require('duniter').statics.quickRun('./index.js')
