Fix "bool object does not support item assignment" error hint.

[Hub-or]

Is your feature request related to a problem? Please describe.

Every time I tried to stop manager with stop_manager_with_all_streams, it hints an error which could be described like function_name -> error: bool object does not support item assignment. And I found out others mentioned this phenomenon with relatively lower frequency, see at: #30.

Describe the solution you'd like.

Change = False to = {} everywhere in Unicornfy can solve this directly without currently known side effects locally.

Describe alternatives you've considered
