Able to remove sub dependencies when they are actually required #6030
Description
Issue description
Pipenv installs sub dependencies when parent package is installed. If we attempt to remove any of its sub dependencies, they are actually removed from the environment but not from lock file. The expected behaviour is that pipenv locking should fail as the parent package cannot work without its dependencies.
Expected result
Pipenv Lock should fail
Actual result
Pipenv Lock was passed and sub-package was removed from environment, but not from the lock. Now lock file and environment are inconsistant.

But pymongo is present in the lock file. Expecting pymongo to be present in lockfile as well as in environment!
