[PATCH] ob-core: Fix indented cached result returning nil

[Bjarte Johansen <bjarte.johansen@gmail.com>]

Fix a problem where a source block would return nil if the result was
cached and it was indented.

* lisp/ob-core.el (org-babel-execute-src-block): Move point to the the
  first character of the result instead of the beginning of the line.

* testing/lisp/test-ob.el
  (test-org-babel/indented-cached-org-bracket-link): Added test to
  to see if the indented cached result returns what it should return.
