vue-router: Hash mode places # at incorrect location in URL if current query parameters exist on page load

Version

3.0.1

Reproduction link

https://codesandbox.io/s/zlvz65rplp

Steps to reproduce

Navigate to myapp.com?foo=bar

What is expected?

Hash is appended before query parameters, to get the final result of myapp.com/#/?foo=bar

What is actually happening?

Hash is placed after parameters myapp.com?foo=bar#/ (also making the query parameters inaccessible with this.$route.query)

---

Note on codesandbox link - unable to place query parameter for initial URL in editor preview - please remove /#/ & append ?foo=bar

Running across this in an instance where user authentication is done outside our app, but client/user identifier is passed to our app in query parameter upon authorization.
