## Current Behavior
<!-- This is the behavior we have today -->

We only ever discover one version of an external dependency for the
file-map.json. This means the `@nx/dependency-checks` lint rule can
produce incorrect failures when multiple copies of a dependency exist
within a workspace.

## Expected Behavior
<!-- This is the behavior we should expect with the changes in this PR
-->

In the file-map.json the project specific version of a package (if
multiple exist) is preferred and therefore the lint rule produces
accurate results.

For example, in a repo where the root package.json has lodash@4.0.0
(which becomes `npm:lodash` on graph) and the foo project has
lodash@3.0.0:
