fix: display Command remaining parts if Args is nil

[kotapeter]

Summary

Since lifecycle@0.15.0 the Command is an array that can contain args too. We just pick the first element of Command.Entries so the remaining parts are gone.

@kotapeter thanks for this. This was an unfortunate oversight in the implementation of these APIs.

I wonder if we want to display both the "always args" (args that are always provided, regardless of user input - these are proc.Command.Entries[1:] if they exist) and the "overridable args" (these are proc.Args). Of course, older APIs (where proc.Args are "always args") would need to be handled differently so as to be displayed correctly, which might bloat this PR. I wonder if in the short-term we can just concatenate them.

@jjbustamante WDYT?
