mu: run initialization command when personal addresses change

Browse source 
When the user changes which addresses mu should consider 'personal',
mu's store should be reinitialized.

After this change, the activation script parses the previously
configured list of addresses and compares it with the new one. If they
differ, it runs the init command even when the store has already been
initialized.
