Site config base will always get / (bug in v1.0.0-alpha.46)

[afeiship]

// routerBase will always get '/'

• version: v1.0.0-alpha.44 is correct
• version: v1.0.0-alpha.46 is wrong

// @vuepress/core/lib/client/app.js
export function createApp (isServer) {
  const routerBase = typeof window !== 'undefined'
    ? window.__VUEPRESS_ROUTER_BASE__
    : (siteData.routerBase || siteData.base)

  const router = new Router({
    base: routerBase,

With version v1.0.0-alpha.44 I was using base in my config which was working fine.
Now in version v1.0.0-alpha.46 it doesn't work anymore, I get a 404 if I want to access the url which is specified via base. But the page works if I manually open /.

For anyone else who wants to fix this locally: you need to downgrade vuepress and core:

npm i vuepress@1.0.0-alpha.44 @vuepress/core@1.0.0-alpha.44

Can you look into this regression?
