Add equals test to check unordered peers and light test style/fix

Hey guys, so I formatted some of the code in the test class to match our styling, made that 2 line fix to Erics test, added the test from my previous PR with an additional unordered peers list equals case check. Let me know what you think and we can make changes as necessary.
