Work around unexpected common_test behaviour
diameter_traffic_SUITE has four layers of nested groups, so when a testcase is run it should get Config from four init_per_group plus one init_per_testcase. This isn't what happens: Config is being accumulated from several init_per_group in some manner that isn't clear, and the skip in the parent commit somehow results in growing test_server_gl:init/1 processes that eventually consume all memory. Replacing rather than prepending to Config in init_per_group works around this, but the common_test behaviour seems wrong.
