--all flag fails to produce output

The standard: “python list_lambdas.py” command completes successfully, but if I add the “–all” flag the following message is produced:

python list_lambdas.py --all

TypeError: a bytes-like object is required, not 'str'

I’m on Windows 10 with Python 3.6.4

Problem reproduced with Python 3. It is because the “Description” field is byte instead of string:

I believe removing the encode('utf-8') should fix that. Creating a fix.

Fixed by #10.
