changes after feedback from matte

We were logging warnings about group names when no group names were
requested. This will clean up Splunk a little bit.

Update Zendesk ticket to correctly add group.

Add logic to hide new audit certs

There's no need to use a string literal in setattr, delattr, or the
two-argument form of getattr.

test fixes

We need to be sure the migrations will work even in the presence of data
from the future.  get_or_create is a problem, because if the data
already exists, there could be more than one record, even if this
migration only creates one.

Please note that this is a squshed commit and the work of:
Symbolist, macdiesel, nedbat, doctoryes, muzaffaryousaf and muhammad-ammar

Properly logging exceptions so we have the complete stacktrace.

Use the number of seconds since the epoch (Jan 1 1970 UTC)
instead of an ISO-formatted datetime string.  This is easier
for credit providers to parse.

Previously, the mobile api did not check for pre-requisite courses
or entrance exams. This change checks for these milestones and then
returns course content accordingly.

Also, I replaced a number of tearDown methods with addCleanup instead.
And also remove some unneeded patch.stopall() calls.
