Make UploadBase use TempFSFile to wrap the temporary file

* The cleanupTempFile() method now only marks it as ready
  for unlinking when unreferenced.
* Pass TempFSFile down the FileRepo call chain so that it
  can build off a5d903860a and allow more fast async writes
  for secondary backends. Previously, the 'store' operation
  used on upload forced sync file change replication writes.
* Also fix bogus method call in LocalFile::publishTo().
