Avoid JSON operations on RsGxsIdGroup::mPgpIdSign

Browse Source 
The field is actually a raw memory chunk even if declared as an
  std::string as result the produced JSON is broken and JSON API clients
  cannot parse the output of methods like rsIdentity/getIdentitiesInfo
A proper fix would be refactoring the whole code to use a proper raw
  memory buffer for that field but given there is no usage for a raw PGP
  signature on a client app as RetroShare library already verify it internally
  workaround the issue by just ignoring that field in JSON serial operations.
