Django has an interesting bug during syncdb. If it knows that a

particular module (say, foo.webapi) has a models.py file, it will then

look for SQL files relative to that. When it does that, it loops through

all modules in INSTALLED_APPS, looking for an app named 'webapi', even

if it isn't the original one it found models in. When it finds one that

doesn't have a models.py (say, djblets.webapi), it will fail with an

error.
The easiest workaround is to just provide a models.py here, so that it

will move along without being so very angry.

I was able to add a models.py to reviewboard/webapi/ without syncdb blowing

up, and with the models appearing in my database.
