org-bbdb-export: use a better description.

* org-bbdb.el (org-bbdb-export): When a link description has been
added by org-export-normalize-links, use path instead (remove the
`bbdb:' prefix).

The existing code handled the case where desc is nil. However, this no
longer occurs, since org-export-normalize-links now automatically adds
a desc to links, with a `bbdb:' prefix that would not usually be
wanted in exported text. The patch results in the same output as
originally intended.
