duplicated subcommand name or alias still happens in 1.7.6 with sub tasks

[yudai-nkt]

When cmdx defines several tasks that have sub tasks, an error reported in #1032 is raised:

tasks:
  - name: foo
    tasks:
      - name: bar
        script: ":"
  - name: baz
    tasks:
      - name: qux
        script: ":"

$ cmdx -v
cmdx version 1.7.6 (29bca03f2177da84d24d1146fba5a8ce4c0ec9fb)
$ cmdx help
parent command [cmdx] has duplicated subcommand name or alias:

If either task has a script, this doesn't happen.

tasks:
  - name: foo
    tasks:
      - name: bar
        script: ":"
  - name: baz
    script: ":"

$ cmdx -v

Wow, the response was so quick! Thanks for the fix and cmdx itself (I love the ergonomics of how cmdx handles flag compared to other task runners).
