Streaming responses for file backend fails if not already in the cache

[davidmegginson]

If a remote resource is not already in the cache for the file backend, the following will return no content:

response = requests.get('http://ourairports.com/countries/CA/PE/airports.csv', stream=True)

Once it's already cached (and not expired), it returns the proper content. Here's the full test script (on first run, it will print empty content; on second run, within 60 seconds, it will dump the full remote content).

import requests, requests_cache

# Use a file backend with 10-second timeout
requests_cache.install_cache(
    '/tmp/test-requests',
    expire_after=60
)

# Get a streaming response, and try reading the raw stream
response = requests.get('http://ourairports.com/countries/CA/PE/airports.csv', stream=True)

# Will be empty if not already in the cache
print(response.raw.read(-1))

(Python 3.5.1, requests-cache 0.4.12)

Confirmed in Python 2.7.12 as well.

Thanks! Fixed.

Thank you. Confirmed working in Python 2.7.12 and Python 3.5.2.
