Fix Host name guess

I was just browsing the code and came across the guess url function [1] In lalsuite I pushed a fix (see [2]) that should be incorporated.

Also you don't have a guess for LLO!

Because the URLs for CIT,LLO and LHO all have 'caltech' in the name it was an easy fix to move the 'caltech' conditional to after the LHO and LLO check.
