Customizable trailing slash behaviour

[tombuntus]

Describe the bug

Currently the router always adds a trailing slash to the basepath.

So if you are at mysite.com/page/one with basepath: '/page/one' and you try to use navigate to update the search params then you end up at mysite.com/page/one/?param=value

Same thing applies if you have no basepath set, so mysite.com would become mysite.com/?param=value

Your Example Website or App

Steps to Reproduce the Bug or Issue

In the example above, just load the page (in a new tab so you can see the query string) and take a look at the address bar.

Expected behavior

I'd expect to be able to specify not add the slash, so that you would end up at mysite.com/page/one?param=value
