[712] html miss <base> when router.base just only have a slash

When I just setting router.base with "/" the html element can't find <base> element It should have a<base href="/">

I tried use a simple project test vue-meta I just set base.href = '/' html work fine .

so , I thinks this belong nuxt.js issue . I tried find problem in nuxt.js source but can't find ....

I propose this issus that because I have a project , in dev test is need a sub folder . but production don't , so , my image url is like ./img/image.jpg so , if html miss base in head , that will break the image .

for now , if I change router.base to '/' , I need add <base href="/"> in app.html template front {{ HEAD }} everytime ... ummm... even I already write it in my CI/CD ...

maybe if can fix this issue will be best . thanks .
