test/old: TODO: skip Test_virtual_replace()

This test exposes a bug (present on current master) in ins_char_bytes()
or somewhere earlier.

Steps to reproduce:

    inoremap <C-D> <Del>
    enew!
    exe "normal a\nabcdefghi\njk\tlmn\n    opq  rst\n\<C-D>uvwxyz"
    call cursor(1,1)
    exe "normal gR0\<C-D> 1\nA\nBCDEFGHIJ\n\tKL\nMNO\nPQR"

or run `TEST_FILE=test_visual.res make oldtest`.
