stack ls dependencies doesn't prune anymore

[akshaymankar]

General summary/comments

This is a bug in stack 2.1.0.1 rc. It is not a problem in 1.9.3.
The pruneGraph function in Stack.Dot seems to have regressed. The tests did not catch this because the properties were either wrong or show for PackageName is no longer being overridden. I could make the tests fail by replacing show with packageNameString.

Steps to reproduce

1. Go to any stack project
2. Run command stack ls dependencies --no-include-base. The bug can also be reproduced using --prune base and it can also be seen in stack dot.

Expected

stdout shows all dependencies except base and its dependencies

Actual

All dependencies including base and its dependencies are printed.
