Denite: <C-j> and <C-k> don't select the next/previous lines
Hi. Looks like any Denite buffer is not moving the selection to the next/previous lines when using `<C-j>` or `<C-k>`. I think this should already be working, based on this:
https://github.com/SpaceVim/SpaceVim/blob/a74237108a78106757e445d335760cd8165bcef4/config/plugins/denite.vim#L111-L113

## Expected behavior
In a Denite buffer, `<C-j>` or `<C-k>` should select the next/previous lines.

## The reproduce ways from Vim starting
`<Space>ff` or any other Denite buffer show this behavior.
