util.import_local fails on apps with compound paths

[mhotwagner]

The local import utility handles apps with simple paths (no-dot), but fails on apps with compound paths (ie, dots). So, this works fine:

INSTALLED_APPS = ('some_app',)
import_local('some_app.SomeClass')

But this fails:

INSTALLED_APPS = ('some_top_level_package.some_module')
import_local('some_top_level_package.some_module.SomeClass')

The issue lies here, in the import_local function:

def import_local(path_to_object)
    path, name = path_to_object.rsplit('.', 1)

    app = path.split('.')[0]  # Assumes the app is the 0th element of the path

    if app not in settings.INSTALLED_APPS:
        raise AssertionError()

Restricting possible app names to the 0th element of the path means we ignore apps with compound paths. Solution should check INSTALLED_APPS for all iterations of the path.
