fix: ssr blocking when skip is true

[ydfzgyj]

When skip in query option is true or can be computed as true, the start method in SmartApollo won't be triggered, and it leads to serverPrefetch can't get a valid resolve function and block server side rendering.

This bug in SSR mode has been driving me mad! Took me a while to narrow it down that it was being caused by a query's skip option. Glad to see a fix.

Even with this fix, skip still is not working in SSR. @ydfzgyj can you confirm? ( I am using quasar ssr mode.)

@beeplin It works fine to me. I think you can try to copy all generated files from my test branch to your project, since we are not sure the vue-apollo.esm.js is the file bundled into your final script.

@ydfzgyj With your test branch it works fine. It turns out that in vue-apollo.esm.js we need to change more than just one place. Thanks!
