  Fix jitterbuffer logging not creating logfiles.

  Three changes made here:
  1) Do not fail if a previous log does not exist (in fact, this is probably
  expected).
  2) Ensure that the file descriptor to write to gets assigned properly. I am at
  a loss as to why assigning safe_fd outside the if fixes this, but it makes
  the if statement slightly less complicated anyway.
  3) Move up the failure message so that the errno of the failure is not
  overwritten by fclose.

  (closes issue #16917)
