add tests for static tabs

Lots of plumbing to allow an asset named python_lib.zip to be imported
by jailed Python code.

This function can find the "python_lib.zip" asset, and is passed down
through ModuleSystem and LoncapaSystem so that capa problems have access
to the zipfile.

Otherwise, if `settings.ENABLE_INSTRUCTOR_ANALYTICS` is set to `False`,
two horizontal rules are rendered consecutively.

 - changed message and added i18n

The changes in 5152 appear to have introduced a
 performance problem on stage, so we're going to
 revert them for now.

- Update key comparisons for Opaque Keys
- Search for 'problem_check' instead of 'save_problem_check' when
  filtering TrackingLogs.

Calling the client root was causing the module store to be modified,
affecting test in other Django applications that rely on the default
state of the module store.

Some tests test were using `CourseFactory` buy not deriving from
`ModuleStoreTestCase`, introducing a course leaks that broke other
unrelated tests.

For microsites, since we don't have a footer override yet for django templates, remove the footer all together

Disable sending activation email also when doing external_auth and setting BYPASS_ACTIVATION_EMAIL_FOR_EXTAUTH=True

This reverts commit 3f159ea5.
