Close debugging terminal if the job fails before it starts

* The debugging terminal [keeps trying](https://github.com/getlocalci/local-ci/blob/4d61c09876078808e0daf50d052d75a9c34e9375/src/utils.ts#L227) to open a REPL
* But if the job fails before it can, the debugging terminal will continue trying, needlessly
* Ideally, this would close the debugging terminal once the job fails, assuming it never opened a REPL
