Jan Varga 0512c7496a Bug 1806490 - Make it possible to track all CreateFileSystemManagerChild requests in FileSystemManager; r=dom-storage-reviewers,jari
It can happen that BeginRequest is called multiple times when the actor doesn't
exist yet. Such situations can't be handled by a single MozPromiseRequestHolder.
