Refactor API: use suggestion-count and #:no-suggestion keyword

- Changed `refactoring-rule-suggested-fixes` to `refactoring-rule-suggestion-count` returning exact-nonnegative-integer
- Replaced `#:suggested-fixes 'none` parameter with `#:no-suggestion` keyword as replacement template
- Updated all test files to use new API
- Tests pass
