Executing `pull_translations` without a locale path setting gives an exception

[willharris]

When I run

./manage.py tx pull_translations

without having specified TRANSIFEX_PROJECT_PATH in the settings I get the following exception:

Executing pull_translations on project test-392

This is with Django 1.6.

It seems that if the path is not explicitly set, then django-transifex tries to figure out where the project is located using a lazy function. There are two problems in the code:

• the lazy function is not properly initialized - it needs str as an additional parameter.
• the lazy function is not a property but a callable, and is not evaluated on access.

There is also the problem that the actual helper function app_settings._get_project_path does not handle the case where the settings file is not top-level in the project. In my case, all my settings are stored in a submodule structure.

The tests do not catch this, because the tests explicitly define TRANSIFEX_PROJECT_PATH.
