patch 8.0.0768: terminal window status shows "[Scratch]"

Problem:    Terminal window status shows "[Scratch]".
Solution:   Show "[Terminal]" when no title was set. (Yasuhiro Matsumoto)
            Store the terminal title that vterm sends and use it.  Update the
            special buffer name.  (closes #1869)
