Allow running dependency tests with the specific webpack version

Investigate first 😄

Did some research, and it's doable. The main issue is with jest, which ignores all files that have node_modules in path, which is case for all files in our case. There is a discussion about this: jestjs/jest#1995. Will do a further research how to avoid the issue.
