misleading output when a package dependency is missing

[davidfirst]

Describe the bug

bit status shows incorrectly "untracked file dependencies" when a dependency (installed as a package) is missing from node_modules.

Steps to Reproduce

1. create two components, A requires B. tag and push to bit.dev
2. import A fro bit.dev
3. delete node_modules inside A component.
4. run bit status.

The output I got is:

> A ...  issues found
       untracked file dependencies (use "bit add <file>" to track untracked files as components):
          a.js -> components/A/b.js

Expected Behavior

A message showing that the package is missing with a suggestion to run bit install.
