Fix broken text on reflection or evil twin deletion. Fix errors with faction flags being sold to NPCs.

A message that was supposed to be displayed to players on reflection/et deletion was not being sent with the required parameters to display it. Caused errors on some screens (and of course didn't display the message). Now sends what=self to SomeoneSaid so when range is checked further up, the message can be displayed to the required objects.

Bonus fix: stop error messages when faction flags are sold to NPCs.
