This will leverage the nose attrib plugin to allow us
to break tests apart on our build system to run
in parallel on separate nodes.

Move tests to one test class

The profile name requires escaping when displayed. Proactively removing since it is not being used. Also discovered some dead code.

Unfortunately, instrospection.get_table_description runs
select * from course_overview_courseoverview, which of course
does not exist while django is calculating initial migrations, causing
this to fail.  Additionally, sqlite does not support information_schema,
but does not do a select * from the table.

Lift the main part of mysql's get_table_description up to the migration itself
and just inspect it directly.  Continue to call the API for sqlite.

Fixes test failures in e4613749

We removed a column in the same release that we removed it
from the model.  This creates a gap where the code still looks for
a column which has been dropped until the new code has been deployed.

The initial fix was to put the column back, but that creates a window
during the alterations where views will error.

This noops the 0008 migration and effectively noops 0009 unless you've
run the old migration.

Previously, course images on the student dashboard were always
served from the localhost, even if the CDN was enabled.
