Fix species tests for method_sources in TSGuess

cluster_tsgs() merges methods into method_sources list, not into the
method string. Updated test_cluster_tsgs to expect the representative's
original method and execution_time. Updated test_as_dict and
test_from_dict to include method_sources in expected output.
