pipenv install --pre doesn't work

[Vayel]

Issue description

pipenv install --pre doesn't work when there are pre-release packages in the Pipfile.

Expected result

The same as:

pipenv lock --pre
pipenv install

Actual result

$ pipenv install --dev --pre
Pipfile.lock not found, creating…
Locking [dev-packages] dependencies…

Warning: Your dependencies could not be resolved. You likely have a mismatch in your sub-dependencies.
  First try clearing your dependency cache with $ pipenv lock --clear, then try the original command again.
 Alternatively, you can use $ pipenv install --skip-lock to bypass this mechanism, then run $ pipenv graph to inspect the situation.
  Hint: try $ pipenv lock --pre if it is a pre-release dependency.

To activate this project's virtualenv, run pipenv shell.
Alternatively, run a command inside the virtualenv with pipenv run.

pipenv install --pre is expected to work because the --pre option is mentioned in pipenv install -h.

it works fine in most cases, i'm guessing it would work fine if you erased everything including the venv and tried it again and that it was a caching issue. Can you check?

@techalchemy Here is the full process:

cd /tmp
mkdir pipenv_3185
cd pipenv_3185
echo '[[source]]' >> Pipfile
echo 'url = "https://pypi.python.org/simple"' >> Pipfile
echo 'verify_ssl = true' >> Pipfile
echo 'name = "pypi"' >> Pipfile
echo '' >> Pipfile
echo '[packages]' >> Pipfile
echo 'black = "*"' >> Pipfile

When I run pipenv install, I obtain:

$ pipenv install --pre

yup I already have a fix up (thus the PR pointing at this issue)
