Subject: [PATCH] Fix error prone babel table output format detection

* lisp/ob-core.el: Test that all elements are in a list are lists or
'hline instead of just the first.

org-babel table output uses different formatting for a list of lists,
but detects it incorrectly causing an error. An example of a block
causing an error is an emacs lisp source block containing just 1 line:
'((1) 2)
