Anchor and router-link do not add the query string to history

[ba55ie]

The navigate method in anchor.ts only adds the path to the history.

The same goes for the router-link. In the navigate method it uses the absolutePath property which also omits the query string.

I started working on a fix, but I don't understand the (undocumented) preserveQuery property in router-link. It seems to use the window.location.search instead of the elements path?
