fix updating flashlight fx after attachment switch (#1154)

* Add next attachment in next frame

- Moves adding of next attachment to next frame
- Allows different flashlight modes to be used and update properly when switching
- Currently switching from one flashlight to another in the same frame whilst the flashlight is on causes the light effect not to update to the new flashlight

Question: Would the localEvent need to be moved into the next frame as well?

* Accessory switch localEvent next frame

* Suggestions from commy for readability
