arity exception when bb tasking with no or an empty task list

[ikappaki]

version

babashka v1.0.165

platform

any

problem

Exception in thread "main" clojure.lang.ArityException: Wrong number of args (0) passed to: clojure.core/max

when bb task'ing with an empty display task list.

A display task list is one that only has tasks with keys that are not symbols or a reprivate or keys start with -.

repro

1. Create a bb.edn file with a tasks list whose name is not a symbol

{
:tasks {:xyz 1}
}

2. Run bb tasks

Fails with exception
