different paths

------------------------------+--------------------
When I run tests using `manage.py test`, the test file
`project/app/tests.py` is used/imported with `__name__ =
"project.project.app.test"`.
When using a relative import in tests.py then, the model appears to get
registered as `project.project.app.model`.
After the database for the tests is being setup, I get the following
error:
> RuntimeError: Conflicting 'model' models in application 'app': <class
'app.models.Model'> and <class 'project.project.app.models.Model'>.
It refers to the same Model, but with different class paths.
This is triggered by / caused when using an relative import from the
tests.py file: `from .models import Model`.
I am running manage.py from the first "project" directory.
`sys.path` contains the directory `.../project/project` and not the
directory where `project.project.app` would be rooted.
With Django 1.6 the `__name__` of tests.py during the import is the same,
but there's no error, since there is no apploader that verifies uniqueness
using the labels/names.
I could not reproduce it with a simple new project/app in Django 1.7.
