[BUG] ob-shell: :shebang changes interpretation of :cmdline

[Max Nikulin]

Hi,

Trying to figure out the origin of the confusion with
"bash -c bash /path/to/file-containing-the-source-code.sh"
I have faced an inconsistency with :cmdline treatment in ob-shell.el. I 
expect same results in the following cases:

#+begin_src bash :cmdline 1 2 3
  printf "%s\n" "$1"
#+end_src

#+RESULTS:
: 1

#+begin_src bash :cmdline 1 2 3 :shebang #!/bin/bash
  printf "%s\n" "$1"
#+end_src

#+RESULTS:
: 1 2 3
