Unable to get file with json content

[Michkov]

How to reproduce:

1. create container, create file with json content eg. '{ }'
2. try to get the file

from pylxd import Client
client = Client()
test = client.containers.get('test')
print(test.files.get('/test.json'))

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/pylxd/client.py", line 88, in _assert_response
    if data['type'] != 'sync':
KeyError: 'type'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    print(nginx.files.get('/etc/helthcheck'))
  File "/usr/lib/python3/dist-packages/pylxd/models/container.py", line 90, in get
    params={'path': filepath})
  File "/usr/lib/python3/dist-packages/pylxd/client.py", line 106, in get
    self._assert_response(response, stream=kwargs.get('stream', False))
  File "/usr/lib/python3/dist-packages/pylxd/client.py", line 92, in _assert_response
    raise exceptions.LXDAPIException(response)
pylxd.exceptions.LXDAPIException: <exception str() failed>

Okay, having had a look at the code, it's because the .files.get(...) implementation re-uses the API .get(...) method which checks if it's JSON and then assumes it must be protocol message and makes assumptions about what must be in the JSON. Hence the failure. I'll try to get this fixed soon.

See #290 for the fix.
