net/py-oauth2: Fix tests from being installed in site-packages

- Patch setup.py to exclude tests from install (CONFLICT) [1][2]
- pkg-descr: Tab->space in WWW: (portlint)
- Bump PORTREVISION

[1] This Python package uses packages=find_packages() with a tests
module in the root that contains an __init__.py file, which results
in the tests module being installed in site-packages. The correct way
of including tests in a pypi package using sdist, while excluding tests
in the root from being installed it to use:

 * packages = find_packages(exclude='tests'),
 * A MANIFEST.in containing "include tests/*" or equivalent
