Using the following code to get tor server descriptors works with stem 1.6, but fails with stem 1.7.

/tmp/stemtest$ cat stem_break.py 
import stem.descriptor.remote
downloader = stem.descriptor.remote.DescriptorDownloader(
desc = list(downloader.get_server_descriptors())
print(f'Got {len(desc)} tor descriptors')
/tmp/stemtest$ python -m pip install
Collecting stem<1.7

Successfully installed stem-1.6.0
/tmp/stemtest$ python stem_break.py
Got 7387 tor descriptors

But using stem 1.7 this fails

/tmp/stemtest$ python stem_break.py

There do not appear to be references to get_server_descriptors function changing in the 1.7 changelog. The environment is python 3.7.1 x64 using ubuntu 18.04.
