Show TestRunFinished.exception consistently in formatters

### 🤔 What's the problem you're trying to solve?

Should a test run fail with some exception unrelated to the test execution itself that exception is kept in `TestRunFinished.exception`. This exception should be provided and presented by various Cucumber formatter implementations.

### ✨ What's your proposed solution?

Most formatters only represent scenarios, but we can create a "synthetic" scenario to represent this failure.

### ⛏ Have you considered any alternatives or workarounds?
