Make compatible with com.tngtech.archunit:archunit-junit5 1.x.x

Currently this library is not working with archunit 1.x.x, due to a breaking change in archunit:

Used version of archunit: 1.0.1

Result when running org.contextmapper.archunitAbstractTacticArchUnitTest#entitiesShouldBeModeledInCML:
`java.lang.IncompatibleClassChangeError: Found interface com.tngtech.archunit.lang.ConditionEvents, but class was expected

Thanks for reporting @marcomima! And sorry that it took so long...
I just released version 1.2.0 of the extension that is now compatible with ArchUnit 1.x.x.
