Added dynamic search for filtering test results.

I ran the test manually with all locations that were present in the location box and noticed SFO Commons does not retrieve results. I am not sure if SFO Commons is some kind of code for San Francisco but that's why I have the check to exclude SFO Commons. If this logic is not correct, let me know. 
<code>locator</code> is usually the suffix here. Rename this to <code>_events_location_links_locator</code>
