Clean up file when file transfer is aborted by remote/local device

Use Case:
1. Send a file from OPP client to OPP Server(DUT).
2. After the incoming file notification comes up.
3. Turn Off Bluetooth and Turn on again or remove battery
   from DUT.

Failure:
- Incoming file notification still present in notification base
- If battery is removed after transfer has started then we see
  incomplete file.

Fix:
Delete File when the transfer is terminated due to
Remote's BT is turned off, remote being taken out of reach or
remote is turned off properly. Also delete the file on the next
reboot while the previous inbound transfer was interrupted by
local device power off, or battery removal.
