Passed tests are printed out in alphabetical order, instead of test-order in koans files

[pavemina]

Very minor, but slightly confusing. The passed test are printed in alphabetical order, instead of the real order as they appear in the koan file, or the test-order.

For example in about_strings.py, tests listed in the following order within the file:

Line 12: def test_create_string_with_double_quotes(self):
Line 19: def test_create_string_out_of_an_integer(self):
Line 26: def test_plus_concatenates_strings(self):
Line 32: def test_plus_will_not_modify_original_strings(self):
Line 42: def test_len_returns_length_of_string(self):
Line 48: def test_strings_can_be_split(self):
Line 55: def test_strings_can_be_joined(self):
Line 61: def test_use_format_to_interpolate_variables(self):
Line 69: def test_strings_can_change_case(self):
Line 77: def test_you_can_get_a_substring_from_a_string(self):
Line 83: def test_you_can_get_a_single_character_from_a_string(self):
Line 89: def test_if_a_string_contains_another_string(self):

But when "contemplating" through the koan, the successful tests are printed alphabetically:
