Fix potential log panic (#82)

If a job uses a [reusable workflow](https://docs.github.com/en/actions/using-workflows/workflow-syntax-for-github-actions#example-of-jobsjob_iduses), the job's steps sequence will be empty.

But in log reporter, we don't check the length of `r.state.Steps`, which may cause panic.

``` go
if v, ok := entry.Data["stepNumber"]; ok {
	if v, ok := v.(int); ok {
		step = r.state.Steps[v]
	}
}
```
