Fixes #516

Description

Store the ConfigDirectory and ConfigFile from the current step, so they can be used by subsequent ImportState steps if not explicitly set

Hey @jeremmfr 👋🏻 , thanks for submitting the PR! #516 definitely looks like a regression from what you reported, which looks like we didn't have a test for.

This will need a changelog and a test covering the original issue, but I can add those before merging.

I've opened a mirror of your PR #520 to actually run our acceptance tests since they unfortunately can't run on forks 🙁 . Will look to review this soon and get a patch released 👍🏻

Hey again @jeremmfr 👋🏻 , I reviewed your changes and did a little digging into the past context of how the regression occurred. We actually had a slightly different approach that I'm proposing to reinstate with #522, so I'm going to close this PR in favor of that one.
