jvpp: stop plugin intialization on first mismatch
Java bindings use get_message_id from jvpp-common to detect if messages known at compile time are avaliable at runtime. In case of missing entry, Java exception is propagated via JNI using (*env)->ThrowNew. But this function does not end code execution so, in order to prevent unexpected behaviour (e.g. calling vl_msg_api_set_handlers with id == 0), get_message_id caller should do it manually.
