Fix running out of entries in `charorder` 

When there are more clients than entries in `charorder`, the following
error occurs:

    W: awesome: luaA_dofunction:77: error while running function
    stack traceback:
            /home/user/.config/awesome/revelation/init.lua:166: in function </home/user/.config/awesome/revelation/init.lua:124>
            (...tail calls...)
            /usr/local/share/awesome/lib/awful/key.lua:43: in function </usr/local/share/awesome/lib/awful/key.lua:43>
    error: /home/user/.config/awesome/revelation/init.lua:166: attempt to index field '?' (a nil value)

This fixes it by skipping setup of `hintindex` in this case.

Fixes https://github.com/guotsuan/awesome-revelation/issues/4.
