[TEST] Invert dependency between :test-generator and :tests-common modules

This is needed to provide ability for declaring new implementations of
  test generators, based on existing infrastructure, which won't add
  dependency on :compiler:tests-common

Also this commit removes implicit dependency on :compiler:tests-common
  from :compiler:tests-common-new
