Subject: [PATCH 1/2] I002 no configuration found when flake8-isort is used
 with flake8 git hook.

Files with changes are moved to a temporal directory when flake8 git hook is used.

$ flake8 --install-hook git

flake8-isort should look for configuration files in the current directory while checking the files in the temporary directory.

Before fix, no configuration is found.

$ git commit -m "Commit message"
[DEBUG] full_path = /tmp/tmpl7f83uys/home/user/src/project/script.py
script.py:0:1: I002 no configuration found (.isort.cfg or [isort] on setup.cfg)

After fix, project configuration is found.

$ git commit -m "Commit message"
[DEBUG] full_path = /home/user/src/project/script.py
script.py:1:1: D200 One-line docstring should fit on one line with quotes
