[Media TTT] Improve our logs around chip removal.

1) Fix our log for removing the chip due to FAR_FROM_RECEIVER state
   (previously, it was logging "ChipStateSender" as the reason, not
   "FAR_FROM_RECEIVER").
2) Add a log for when we ignore a removal event.

Fixes: 246574567
Test: manual: verified MediaTttSender logs
Test: media.taptotransfer tests
