create_or_update_partner error when 'code' is too long

[danielmcquillen]

The create_or_update_partner command doesn't gracefully handle a 'code' string that it considers too long. The first time I ran this command (i.e. no existing partners), I used a code 15 characters long. Here's the error I got...

Traceback (most recent call last):
  File "/edx/app/discovery/venvs/discovery/lib/python3.5/site-packages/django/db/models/query.py", line 480, in update_or_create
    obj = self.get(**lookup)
  File "/edx/app/discovery/venvs/discovery/lib/python3.5/site-packages/django/db/models/query.py", line 387, in get
    self.model._meta.object_name
course_discovery.apps.core.models.DoesNotExist: Partner matching query does not exist.

During handling of the above exception, another exception occurred:
