pipenv: pipenv respects version constraint from incorrect python version

drf-yasg package has 2 Django version constraints:

Django (>=1.11.7); python_version >= "3.4"
Django (<2.0,>=1.11.7); python_version <= "2.7"

pipenv uses 2.7 one even when invoked in python 3.6 virtual env.

$ python -m pipenv.help output

Pipenv version: '11.10.0'

Pipenv location: '/Users/dspeck/work/test/.venv/lib/python3.6/site-packages/pipenv'

Expected result

pipenv lock produces Pipfile.lock

Actual result

Pipenv cannot resolve dependencies with the following error:

verbose output 
.venv ❯ pipenv lock --verbose
Courtesy Notice: Pipenv found itself running within a virtual environment, so it will automatically use that environment, instead of creating its own for any project. You can set PIPENV_IGNORE_VIRTUALENVS=1 to force pipenv to ignore that environment and create its own instead.

So we should allow duplicate entries with different markers in Pipfile too. (which is not supported by my previous commit)

Pipenv uses whichever thing is called python and has precedence unless you tell it specifically which python to create the environment with or you set PIPENV_DEFAULT_PYTHON_VERSION. Use pipenv install --python=3.6 or pipenv install --three or pipenv install --python=/usr/local/bin/python3.6
