fix: match patterns relative to root

I was surprised fixer patterns (used to determine which fixers to run)
are applies to the parent directory, not the repo root
directory. Danny Hooper (the author of the extension) seemed to agree
that it's better to apply them to the repo root, so that's what this
patch does.
