i2p: destroy the session if we get an unexpected error from the I2P router

From https://geti2p.net/en/docs/api/samv3:

  If SILENT=false was passed, which is the default value, the SAM bridge
  sends the client a ASCII line containing the base64 public destination
  key of the requesting peer

So, `Accept()` is supposed to receive a Base64 encoded destination of
the connecting peer, but if it receives something like this instead:

  STREAM STATUS RESULT=I2P_ERROR MESSAGE="Session was closed"

then destroy the session.
