Test generator: improve import statements in generated tests

- delete unused "junit.framework.Assert" import
- delete import of the abstract super class, because it always happens to be in
  the same package
- reorder other imports in such way that "Optimize Imports" action in IDEA will
  mostly have no effect in generated tests. However this will still happen in
  tests without any nested test cases (useless imports of InnerClasses etc.)

beforehand
