Cannot get help for "bob archive clean"

[jkloetzke]

Describe the bug

If outside of any recipes:

$ bob archive clean -h
Parse error: No recipes directory found in recipes

But even if you're in a project, you will most likely get:

$ bob archive clean --help
Error: None of the archivers supports the archive command. Maybe you did not select any (-b/--backend)?

Steps to reproduce
Just call the commands as above.

Context

• Bob version: 1.2.0rc1
