Cache is being cleaned up to quickly for validation files

[jquick]

When setting the audit option to export to a json-file in the config it is not able to write. It use to work but looks like it broke with this change:

b403f0b

This cleans up the cache before the json-file can be looked at manually.

I am running into a similar problem where I need to check and even use some files that are in the sandbox in my inspec tests but dokken cleans them up before inspec runs.
