org-bibtex-read: Do not add nil when there is no entry at point 

* lisp/ol-bibtex.el (org-bibtex-read): Previously, when there is no
entry at point, `nil' would be added to `org-bibtex-entries' causing
errors later, i.e. upon calling org-bibtex-write.  Now, nil is never
pushed to `org-bibtex-entries'.
