kickstart.nvim currently spews 'attempt to index null value' errors at startup

[feoh]

Describe the bug

I goofed and merged PR #373 without thoroughly testing it.

So now you get:

Error detected while processing /Users/cpatti/.config/nvim/init.lua:
/Users/cpatti/.config/nvim/init.lua:467: attempt to index a nil value
/Users/cpatti/.config/nvim/init.lua:467: attempt to index a nil value
/Users/cpatti/.config/nvim/init.lua:467: attempt to index a nil value
/Users/cpatti/.config/nvim/init.lua:467: attempt to index a nil value

On startup.

To Reproduce

1. Pull latest kickstart.nvim from master
2. Start Neovim
