Subject: vim-patch:8.1.1756: autocommand that splits window messes up window
 layout

Problem:    Autocommand that splits window messes up window layout.
Solution:   Disallow splitting a window while closing one.  In ":all" give an
            error when moving a window will not work.
https://github.com/vim/vim/commit/1417c766f55e5959b31da488417b7d9b141404af

Expected error number was changed to E242 in Vim in patch 8.2.1183, and
patch 8.2.2420 (which has already been ported) made the test no longer
throw E249 in Vim, so just use E242 in the test.
