Don't revert type-aware project settings on reimport

This basically reverts 47c7441cbd890627ef25a131950a224b6c50b2b5, but I'd like to
find a way to respect these defaults on first load only.

This is really annoying, especially on projects where type-aware is completely broken. I've broken the intention of the original commit above, so I'm open to suggestion about what where might be a better place to enable these defaults (without affecting reimport).
