[2pt] Direct / Root dependency counts swapped

[codificat]

Describe the bug

It seems that the numbers for Direct and Root depencencies in the summary are reversed, i.e. Root is showing the number of direct dependencies, while Direct is showing the number of root level dependencies.

To Reproduce Steps to reproduce the behavior:

1. Have a Pipfile with a single dependency on it, nltk
2. Request a stack advise
3. Check the advise results in the search UI
4. Notice that the Dependencies Summary box shows wrong numbers

Expected behavior

There should be only 1 root package (nltk) and 4 direct (nltk's dependencies).

Screenshots

Additional context

Here is the advise I looked at: https://thoth-station.ninja/search/advise/adviser-220524121408-dc0af1f4d2307c27/summary

These metrics will be removed in a future update that better represents what the user wants to see. We will make sure to fix this issue when that happens.
