Specifying a version as '==X.X.*' has different behavior than '>=X.X.X'. This causes issues with deployment

[artificial-aidan]

Issue description

When you run pipenv install package==X.X.* the Pipfile.lock gets a package added to it with a hash, and a version specifier of X.X.*. If this package then gets updated, and you run pipenv install --deploy it fails because it installs the updated version, and the hash doesn't match.

Expected result

I expect that when I install a version it will lock a specific version number so I can deploy with a Pipfile.lock. This is how pipenv install package>=X.X.X works.

Actual result

Does not pin a version

Steps to replicate

pipenv install <package-name>=X.X.*
Look at the lockfile, the version will be specified as X.X.*
