WrongDirection not detected when subpackages are used

[ascheman]

I think there is an error the example:

Add an error

Introducing two new classes (cf. ascheman/uneven-modules@2138b29):

• SpecialFacade in package facade
• SpecialBusiness in package in business

The latter imports the former which is an architecture violation which is detected and the build fails.

And make it disappear

If the two classes are moved to sub-packages (cf. ascheman/uneven-modules@8f29af9), e.g.,

• SpecialFacade to package facade.special
• SpecialBusiness to package business.products

The architecture violation magically vanishes and the build is OK. I would expect that even access from/to sub packages is disallowed by the architecture blueprint.

The two commits in my fork show that the error is detected but vanishes if the Classes are moved to sub packages.

I'll flag this as a bug as you suggested b/c I introduced the concepts "PackageLevel" and "TransitivePackageDependencies" to prevent exact this situation.

Thanks to @jensnerche and @DirkMahler I could finally fix the problem and propose a working solution. PR is following soon.
