Fix wrong default *_event_detect values (must be True). Add test to check, that we cannot subscribe to the event if they are no not enabled

We used as default value for command type None, and if so - started to look for type hints. But None can also mean, that user wants to force  command to be DevVoid. Now we use as default option internal no-opt class

Backport !945, !954, update docs and bump version for 10.1.2 release

See merge request !956
