Slow test analysis runs even when there's no slow tests

[ngan]

We don't always build every single test but it looks like the slow test analysis always runs even when there's no slow test:
https://github.com/KnapsackPro/knapsack_pro-ruby/blob/master/lib/knapsack_pro/base_allocator_builder.rb#L55

No slow tests being that slow_test_files = get_slow_test_files is an empty array.

An optimization to make would be to see if we actually got any slow tests back from the get_slow_test_files call. If we got an empty array, it should just bypass the analysis completely.

Thanks for the suggestion.

We are aware of that and plan to address this. I'm closing this as it's a dup of: #223.
