Retest defaults to test_*.rb pattern even when *_test.rb file exists

[AlexB52]

Here is the original issue

• When updating the file test_options.rb
• I expect retest to select test_options_test.rb
• and not to return the file test_options.rb

I think this is also related to this issue:

• Given there are three files test_fixtures.rb, fixtures.rb and fixtures_test.rb
• A change in fixtures.rb selects test_fixtures.rb by default
• When it should offer the option to choose between test_fixtures.rb and fixtures_test.rb

When a file is discovered with the pattern test_*.rb we do not continue searching for other file patterns which could potentially be more appropriate.
