[Orgmode] [BUG] org-exp.el: Broken Internal Links

[Jambunathan K]

See Heading2 for description of the bug. This bug has been there since
time immemorial.

# Input Org file

* Heading1
  
* Heading2
  
  Link to [[Heading1]] is OK. Link to [[Heading3]] is broken. To fix this,
  org-link-search in org-export-target-internal-links should avoid
  matching on the self somehow.
  
* Heading3
