title: Folders not showing up in Bucket storage
body: <p>So my problem is that a have a few files not showing up in gcsfuse when mounted. I see them in the online console and if I 'ls' with gsutils. 
  Also, if If I manually create the folder in the bucket, i then can see the files inside it, but I need to create it first. Any suggestions?
  <br><br>
  <code>gs://mybucket/
      dir1/
          ok.txt
          dir2
              lafu.txt</code>
  <br><br>
  If I mount mybucket with gcsfuse and do 'ls' it only returns dir1/ok.txt.
  Then I'll create the folder dir2 inside dir1 at the root of the mounting point, and suddenly 'lafu.txt' shows up.</p>
