patch 9.1.0035: i_CTRL-] triggers InsertCharPre

Commit: https://github.com/vim/vim/commit/7d711fe2092d0438d2df5054df735ec34926e2bc

    patch 9.1.0035: i_CTRL-] triggers InsertCharPre

    Problem:  i_CTRL-] triggers InsertCharPre
    Solution: Return if CTRL-] is received. InsertCharPre
              is supposed to be only used for chars to be inserted
              but i_CTRL-] triggers expansion and is not inserted
              into the buffer (altermo)

    closes: #13853
    closes: #13864
