lokview: be robust to LibreOfficeKit not being available

When LibreOfficeKit is not available, we still create a LOKView
preview.

We then need to check whether the internal LOKDocView exists before
calling a method on it, or we will trigger an exception that will
prevent the regular error page from kicking in.
