Before edx-platform version 19ba691,
only `lms_web_url` was exposed from the course
blocks API. Now that the API also exposes
`legacy_web_url`, we can stop falling back
to `lms_web_url` when `legacy_web_url` is
absent.

As part of making the new courseware experience the
default for staff, the LMS /jump_to/ links that are
exposed by the Course Blocks API via the `lms_web_url`
field will soon direct users to whichever experience
is active to them (instead of always directing to
the legacy experience & relying on the learner
redirect).
Because of this, the MFE can no longer rely on
`lms_web_url` to land a staff user to the legacy
experience. However, the aformentioned change
will also introduce a `legacy_web_url` field
to the API, which we *can* use for this purpose.

Valid courseware URLs currently include:
* /course/:courseId
* /course/:courseId/:sequenceId
* /course/:courseId/:sequenceId/:unitId
In this commit we add support for:
* /course/:courseId/:sectionId
* /course/:courseId/:sectionId/:unitId
* /course/:courseId/:unitId
All URL forms still redirect to:
/course/:courseId/:sequenceId/:unitId
See ADR #8 for more context.
All changes:
* refactor: allow courseBlocks factory to build multiple sections
* refactor: make CoursewareContainer tests less brittle & stateful
* feat: handle courseware paths more liberally
* refactor: reorder, rename, & comment redirection functions
