Honor cl_allow_uid2name 0 when cl_allow_uidtracking is 1.

In an attempt to display better nick information I've overwritten the provided nick (in this case none) w/ what was on the player record. This is wrong - if uid2name is 0, thus leading to no nick provided, that means I should show "Anonymous Player". This ends up being a little silly when uidtracking is 1, because a person can just click on the "Anonymous Player" link to see who was actually playing :D.
