not working on model queries not leveraging cache

[Chad Sollis]

Exact same issue as this issue however I am using version 0.9.8 of orator and 0.1.1 orator-cache.

I setup cache like this:

from orator_cache import DatabaseManager, Cache
stores = {
        'default': 'file',
        'stores': {
            'file': {
                'driver': 'file',
                'path': '/var/tmp'
            }
        }
    }
db = DatabaseManager(config, cache=Cache(stores))

models like this:

from orator import Model, SoftDeletes
Model.set_connection_resolver(db)
class RevenueModel(SoftDeletes, Model):
...

getting this error:

TypeError: init() missing 1 required positional argument: 'cache'

Traceback:

For what it's worth, I really love this ORM. You have done a great job.
