Repass the arguments to CoreStore

[leonardotc]

class Corestore extends ReadyResource {
  constructor (storage, opts = {}) {
    super()

    this.root = opts.root || null
    this.storage = this.root ? this.root.storage : Hypercore.defaultStorage(storage, { id: opts.id, allowBackup: opts.allowBackup })
    this.streamTracker = this.root ? this.root.streamTracker : new StreamTracker()
    this.cores = this.root ? this.root.cores : new CoreTracker()
    this.sessions = new SessionTracker()
    this.corestores = this.root ? this.root.corestores : new Set()
    this.readOnly = opts.writable === false
    this.globalCache = this.root ? this.root.globalCache : (opts.globalCache || null)
    this.primaryKey = this.root ? this.root.primaryKey : (opts.primaryKey || null)
    this.ns = opts.namespace || DEFAULT_NAMESPACE
    this.manifestVersion = opts.manifestVersion || 1

    this.watchers = null
    this.watchIndex = -1

    this._findingPeers = null // here for legacy
    this._ongcBound = this._ongc.bind(this)

    if (this.root) this.corestores.add(this)

    this.ready().catch(noop)
  }

The corestore allows to overwrite the actual storage among other things including the components that use RockDB. I tried to use a mock system to mock that stuff but it grew quick in complexity due to issues related to node modules, sdm etc. The easiest solution is to re-pass arguments to the CoreStorage like a goodboi. Wiht that I can even use mafi's best kept secret: test-tmp.

This scenario is more aggravated because the constructor is already invoking the method that will trigger the whole ReadyResource lifecycle. Even dirty solutions are a bit more involved.
