Logs error on lost info about recorded timing for test files due to missing json files in Queue Mode

[ArturT]

Problem is related to knapsack_pro Queue Mode

Sometimes users have in their tests code that clears tmp directory. For instance, user can have RSpec hooks like after(:each) or after(:suite) that remove the content of tmp folder.

knapsack_pro gem uses tmp/knapsack_pro/queue/ directory to store json files with a recorded time of tests.

Introduced change

This pull request adds log error to notify the user when the tmp/knapsack_pro/queue/ directory is empty even when some test files where executed. It means the user has probably RSpec hook or some other code that clears tmp directory which breaks knapsack_pro.

Another reason might be that you forgot to add Knapsack::Adapters::RspecAdapter.bind in your rails_helper.rb or spec_helper.rb. Please follow the installation guide again: https://docs.knapsackpro.com/integration/
