Describe the reason for change

The change originally made to fix an issue with taxonomy loading after updating the Label Config made it such that the preview was always a step behind changes that were made by the user. This addresses this by moving all the associated logic of updating and initializing to the same useEffect.

The following now occurs:

• Only a single initialization takes place for the preview
• Updates apply consistently on change of either config or task data.
• Only a single destroy will take place when the preview unmounts (important fix to the original issue!)
