JavaHL: Exceptions in LogMessageCallback.singleMessage should abort the log immediately

If e.g. a RuntimeException is thrown in
LogMessageCallback#singleMessage, it's not processed in
LogMessageCallback::singleMessage and the log is continued nevertheless:

(1) At line 77 in LogMessageCallback.cpp, there should be returned an
appropriate error code.

(2) After line 122, JNIUtil::isJavaExceptionThrown() should be called
and there should be returned an appropriate error code.

In both cases, the returned error code should result in stopping the
low-level log; rethrowing the Exception in RemoteSession::getLog won't
be necessary, as this can be established easily from within client code
itself.
