[BUG] org-agenda-open-link does not open bbdb links

[Matt Lundin <mdl@imapmail.org>]

The function org-agenda-open-link does not open bbdb links.

The reason is that bbdb agenda lines contain links that are not found in
the entry. 

Because the agenda line is added to the strings scanned by
org-offer-links-in-entry, it is added to the list of links (lk). I.e.,
both buffer and lk are defined, which triggers the first cond statement.
The function then proceeds to search for this link in the buffer. It
does not find it, since a bbdb-anniversary entry typically looks like
this:

* Anniversaries
  :PROPERTIES:
  :CATEGORY: anniv
  :END:
%%(org-bbdb-anniversaries)

But as a result, the function org-offer-links-in-entry never gets to the
second cond statement, which would indeed open the link found in the
agenda buffer.

It seems to me that feeding the agenda line as a "prefix" to
org-offer-links-in-entry is redundant, since the second cond statement
explicitly looks for links in the agenda line.

The following change fixes the problem, but before I submit it as a
properly formatted patch, I want to make sure that it does not interfere
with some other functionality.

Best,
Matt
