isort config inconsistent between local and travis

[euri10]

Describe the bug
if you run isort locally, it sorts the fastapi package as a 3rd party package, so once you push a branch on travis, isort there will fail
I think PyCQA/isort#541 (comment) describes it well

To Reproduce

Expected behavior
to run isort locally and have travis succeed without having to change fastapi import orders

Environment:

• OS: debian buster
• FastAPI Version [e.g. 0.3.0], get it with: 0.5.0

import fastapi
print(fastapi.__version__)

• Python version, get it with:

python --version

I'm sorry for the inconvenience, this was actually lack of documentation.

The trick is to install FastAPI in your local environment with:

flit install --symlink

that way isort can detect FastAPI as an installed package and sort all the files accordingly.

I just added contributing guidelines here that should help setting up the local environment:

oO thanks for the hint, today I learnt something, will ditch that "fix" 🐢

That actually bit me too at the first iterations 😬
