While completing #444, I found various bugs and to make #444 purely about vectorising wrappers, this PR includes all of the bug fixes

List of bugs

• Fix VectorObservationWrapper.reset that is not updated to the new API with obs, info
• Fix VectorObservationWrapper.step to remove additional observation
• Fix VectorActionWrapper.step to correctly reference self.actions rather than self.action
