Fix YouTube API connection failure

Essentially, as described in googleapis/google-api-python-client#1109 and googleapis/google-api-python-client#876 - since version 2.0.0 google-api-python-client has included static documents for all Google Discovery APIs. To use them, you'd need to tell PyInstaller to include those static .json files in your build or use static_discovery=False which causes the library to dynamically download the API's discovery file from Google on build(). Otherwise, pyinstaller builds will fail.
