Issue #272 - Fix SOP violation in tests (session cookies will now work)

BIG THXXXXXXXXXXXXXXXXXXX to @vladikoff 

Note, Travis will probably fail because now that logging in is "sticky", the tests counting the number of browse categories will include "Issues reported by Me". So this fix revealed a flaw in our testing. 

Will provide a fix for that issue tonight or tomorrow then ask for review (so we don't have to accept a pull which breaks the build on master).
