Remove "Not logged in" from the personal URLs array

Remove "Not logged in" from the personal URLs array

The array of personal URLs should only contain links to the personal tools of the
user. "Not logged in" is a status message, not a personal URL, so it should not
appear in that array. The status should instead be indicated to the user by the
skin itself in whatever way seems best for the skin in question.

The following patches depend on this one to reintroduce the message:
* Vector skin: Ic560d3fd
* Monobook skin: I7001e311
