AutoPkg should rebuild missing recipe map on demand

[gregneagle]

THIS IS ONLY INTENDED FOR AUTOPKG BETAS.

Describe the problem
autopkg should always build a recipe map if one is missing.
If an AutoPkg user installs 3.0 RC1 or uses the the dev branch as of this commit: 1831864 if the next thing they do is attempt to run a recipe (a common thing to do with AutoPkg), they are greeted with this error:

Cannot read the recipe map file!
Cannot parse the recipe map - it's either missing or invalid!
Try adding or removing a repo to rebuild it.

AutoPkg output

$ autopkg run GoogleChrome.download
Cannot read the recipe map file!
Cannot parse the recipe map - it's either missing or invalid!
Try adding or removing a repo to rebuild it.

Expected behavior
autopkg should almost never output this error message.
autopkg should always build a recipe map if one doesn't exist.

Version (please complete the following information):

• OS version: 13.5.1
• AutoPkg Version: commit 1831864

I've hit a version of this as well.

It seems like the error should trigger a build/rebuild of the map and a retry.

This fails to ever list the repos defined even though they are due to the map file error:

python ..\autopkg\Code\autopkg repo-list
Cannot read the recipe map file!
Cannot parse the recipe map - it's either missing or invalid!
Try adding or removing a repo to rebuild it.

then this ends up fixing it, while also giving the info:

python ..\autopkg\Code\autopkg info        
Cannot read the recipe map file!
Cannot find or read the recipe map! Creating it now...
Current preferences:
{'RECIPE_REPOS': {'C:\\Users\\jgstew\\Library\\AutoPkg\\RecipeRepos\\com.github.autopkg.hansen-m-recipes': {'URL': 'https://github.com/autopkg/hansen-m-recipes'},
                  'C:\\Users\\jgstew\\Library\\AutoPkg\\RecipeRepos\\com.github.autopkg.homebysix-recipes': {'URL': 'https://github.com/autopkg/homebysix-recipes'},
                  'C:\\Users\\jgstew\\Library\\AutoPkg\\RecipeRepos\\com.github.jgstew.jgstew-recipes': {'URL': 'https://github.com/jgstew/jgstew-recipes'}},
 'RECIPE_SEARCH_DIRS': ['.',
                        '~/Library/AutoPkg/Recipes',
                        '/Library/AutoPkg/Recipes',
                        'C:\\Users\\jgstew\\Library\\AutoPkg\\RecipeRepos\\com.github.jgstew.jgstew-recipes',
                        'C:\\Users\\jgstew\\Library\\AutoPkg\\RecipeRepos\\com.github.autopkg.hansen-m-recipes',
                        'C:\\Users\\jgstew\\Library\\AutoPkg\\RecipeRepos\\com.github.autopkg.homebysix-recipes']}

And after that, repo-list works again.
