Doesn't play nicely with Vim 8 packages

[lithammer]

Loading vim-lsc using packages instead of vim-plug causes issues with loading order. For example, the BuffersOfType function in plugin/lsc.vim always return an empty list during startup. So servers are never started automatically (you have to explicitly call LSClientEnable).

This is with let g:lsc_auto_map = v:true. I know that vim-polyglot also had a bunch of issues with loading order of the native package system vs vim-plug.
