vim-patch:8.0.1494: no autocmd triggered in Insert mode with visible popup menu

Problem:    No autocmd triggered in Insert mode with visible popup menu.
Solution:   Add TextChangedP. (Prabir Shrestha, Christian Brabandt,
            closes vim/vim#2372, closes vim/vim#1691)
            Fix that the TextChanged autocommands are not always triggered
            when sourcing a script.
