OPP: Fix file receive issue after NFC use case.

Use case:
1) Turn on Android Beam
2) Receive a file from peer through NFC
3) After file transferring complete receive another
  file from same device via OPP.

Result:
Not observed any file receiving UI notifications in DUT.

Root cause:
DUT received connect request from same peer before expire NFC white list timer,
so DUT auto accepted incoming file and not shown any UI notifications.

Fix:
Remove Whitelist entry after transferring complete to avoid UI related
issues in profile.
