[BREAKING CHANGE]: Scoped containers no longer use the parent's cache for Lifetime.SCOPED registrations (#92)
Change the "react-native" module path to use awilix.browser.js (#104)
Update packages

Awilix v4 corrects a misunderstanding in how the scoped caching should work. For full context, please see issue #92, but the TL:DR version is that prior v4, scoped registrations (Lifetime.SCOPED / .scoped()) would travel up the family tree and use a parent's cached resolution if there is any. If there is not, the resolving scope would cache it locally.

While this was by design, it was not very useful, and it was designed based on a misunderstanding of how Unity's HierarchicalLifetimeManager works. In v4, Lifetime.SCOPED now works the same way: the container performing the resolution also caches it, not looking outside itself for cached resolutions of Lifetime.SCOPED registrations.

A prime use case for this is having a scoped logger, as well as a root logger. This is actually what prompted this change.

// logger.js
export class Logger {
  constructor(loggerPrefix = 'root') {
    this.prefix = loggerPrefix
  }

  log(message) {
    console.log(`[${this.prefix}]: ${message}`)
  }
}

// app.js
import { Logger } from './logger'
import { createContainer, asClass, InjectionMode } from 'awilix'

const container = createContainer({
  injectionMode: InjectionMode.CLASSIC,
}).register({
  logger: asClass(Logger).scoped(),
})

const scope = container.createScope()
scope.register({
  loggerPrefix: asValue('dope scope'),
})

const rootLogger = container.resolve('logger')
const scopeLogger = scope.resolve('logger')

rootLogger.log('yo!') // [root]: yo!
scopeLogger.log('wassup!') // [dope scope]: wassup!

Prior to v4, the scopeLogger would have resolved to the same as rootLogger because it would ask it's ancestors if they had a logger cached. Now it works as you would probably expect it to: it keeps it's own cache.
