Summary: 

When org-store-link is invoked on a headline in indirect buffer (as in a
capture buffer), hyperlink gets created to the file and NOT the
headline. This is a bug.

The attached patch fixes this.

Setup:

# ~/.emacs

(defun my-conversation-id ()
  (interactive)

  (remove-hook 'org-capture-before-finalize-hook 'my-conversation-id)

  (let ((org-link-to-org-use-id t))
    (call-interactively 'org-store-link)
    )
  )


# org-capture-templates

 ("x" "Conversations" entry
  (file+headline "~/conversation.org" "Conversations")
  "%(progn (add-hook 'org-capture-before-finalize-hook 'my-conversation-id) \"\")** Note taken on %U\n   %?  " :prepend t :empty-lines 1)

Steps for reproduction:

Trigger org-capture for the above capture entry.

Examine conversation.org before/after the patch is applied. Note the
absence/presence of IDs for the captured entry. 

Check for the stored links using C-c C-l. Note the file/headline links.

# file conversation.org before and after the patch

* Conversations
