Re-enable test_live_reconfiguration_del_project

More or less straight forward port. Because of the consolidation of test
names in v3 layout, test1-project1 no longer exists, so we have to pass the
project name into getJobFromHistory.

Since the next test down was deemed irrelevant, squashing its removal
onto this patch to reduce reviewer load.
