vim-patch:partial:8.0.1592: terminal windows in a session are not properly restored

Problem:    Terminal windows in a session are not properly restored.
Solution:   Add "terminal" in 'sessionoptions'.  When possible restore the
            command running in a terminal.

https://github.com/vim/vim/commit/4d8bac8bf593ff087517ff79090c2d224325aae6

Tests only. Nvim has no equivalent to "norestore" yet.
