Disable and unregister some FolksDummy.PersonaStores.
For each of the persona stores in stores
, disable it (if it was enabled) and unregister it from the backend so that it
cannot be re-enabled using Folks.Backend.enable_persona_store or
Folks.Backend.set_persona_stores.
Folks.Backend.persona_store_removed will be emitted for all persona stores in stores
which were
previously enabled. After all removal signals are emitted, a change notification for
Folks.Backend.persona_stores will be emitted (but only if at least one removal signal is emitted).
