-    Make sure that import hack works as expected.

-    Jedi does an import hack (see: jedi/__init__.py) to have submodules
-    with circular dependencies.  The modules in this circular dependency
-    "loop" must be imported by ``import <module>`` rather than normal
-    ``from jedi import <module>`` (or ``from . jedi ...``).  This test
