Summary of edits:
renter_test.go - reordered tests so that they are cleanly grouped and alphabetized so it is easier to work with. combined interrupt tests into TestRenterInterrupt so that as a group they can be run in parallel to improve the runtime and not error out due to too many files open
testgroup.go - updated AddNodes to return the nodes added. Needed this in order to combine the interrupt tests.
testgroup_test.go - added unit test for AddNodes to confirm the node added was returned.
