I guess that Pronto::Git::Patch#new_file_full_path may return unexpected value for Pronto::Runner.

$ cd /tmp
$ git clone https://github.com/prontolabs/pronto.git
$ cd pronto
$ bundle
$ git worktree add ../t
$ echo '# test' >> Gemfile
$ echo '# test' >> ../t/Gemfile
$ bundle exec ruby -Ilib -rpronto -e 'Pronto::Git::Repository.new(".").diff(:unstaged).each {|p| p p.new_file_full_path }'
#<Pathname:/tmp/pronto/Gemfile>
$ bundle exec ruby -Ilib -rpronto -e 'Dir.chdir("../t"); Pronto::Git::Repository.new(".").diff(:unstaged).each {|p| p p.new_file_full_path }'
#<Pathname:/tmp/pronto/.git/worktrees/Gemfile>

When I apply the following patch, new_file_full_path returns #<Pathname:/tmp/t/Gemfile>.
