Fix additional Javadoc errors found in audit

- ConnectionTypeResponse.fromString() Javadoc said it creates a
  ConnectionTypeResponse; it returns the ConnectionType enum.
- NetworkDeserializer constructor Javadoc had a malformed inline tag
  (@{code instead of {@code).
- WebServiceProvider/WebServiceClient insights() @return said
  "Insight model" rather than "Insights model".
- Corrected "a AnonymousIpResponse"/"a AnonymousPlusResponse" to
  "an ..." in DatabaseProvider and DatabaseReader Javadoc.
