--cov does not apply with source_pkgs

[kandji-gregg]

Summary

adding --cov does not work if source_pkgs is used instead of source in the .coveragerc file

Expected vs actual result

I expect adding --cov to narrow the results to the specified directories but it ignores it if source_pkgs is defined.
