Handle exception when running rspec (Queue mode)

[thukim]

Issue: When running rspec with the queue mode and having exception, the existing code doesn't trigger the after_subset_queue and after_queue hooks

This PR handles exception in the above scenario that:

• It logs the exception which causes Knapsack Pro to exit/abort (debug mode)
• Triggers the after_subset_queue and after_queue
• Prints the summary before exiting: Unexecuted tests, pending tests and failed tests
  After that, it will re-raise the exception.

Please let me know if there is anything I need to update/address in this PR. Thank you!
