vim-patch:8.2.1781: writing to prompt buffer interferes with insert mode

Problem:    Writing to prompt buffer interferes with insert mode.
Solution:   Use win_enter() instead of just setting "curwin". (Ben Jackson,
            closes vim/vim#7035)
4537bcc889

Vim test will be skipped, so add a Lua test.
The problem boils down to the use of aucmd_restbuf in a callback, so just test
that (via nvim_buf_set_lines).
