Some anchor links produce a bad row in the pagelinks table (empty pl_title value) and the error "Invalid title in result set;" on Special:WantedPages.

Here is a simple test case. Create a wiki article containing these two lines:

[[#test]]
== test ==

In the pagelinks table, you get:

mysql> select * from pagelinks where pl_title = '';
+---------+--------------+----------+
| pl_from | pl_namespace | pl_title |
+---------+--------------+----------+
|     717 |            0 |          | 
+---------+--------------+----------+
1 row in set (0.01 sec)

This happens in 1.14.0 but not in 1.13.2.  In my 1.13.2 wiki, the pagelinks table has zero rows with an empty pl_title, so I assume this new behavior is a bug.
