Making false-positive errors since v3.0.0, if any specified jobs aren't ran

[kachick]

What

Extracted from #754 (comment)

If "wait-list" is used, and that job doesn't run at all (in my case, the job I'm waiting for doesn't always need to run), we get: throw new Error("No targets found except wait-other-jobs itself"); I think perhaps the proper fix here, if possible, might be to add a third parameter to wait-list to indicate the job is optional, or (much easier) just an overall "jobs-might-not-exist" parameter that skips that Throw? Because if it's not

How

• the guard message applied since 3.0.0, just dropping might be enough
• add options to handle that?

Add option to avoid this problem in #762 and released it with v3.1.0 🙏
