BUG: query string is wiped out when navigate() is called with path only

[MaxMotovilov]

A call to navigate(path) always wipes out the query string. It happens because

hookrouter/src/router.js

Line 100 in 53d65f8

window.history[`${replace ? 'replace' : 'push'}State`](null, null, finalURL);

uses only the path and the code in

hookrouter/src/router.js

Line 105 in 53d65f8

setQueryParams(queryParams, replaceQueryParams);

does not execute when queryParams are null.

Probably answers the question in #99

Current workaround is to always pass in {} for queryParams as well as false for replaceQueryParams.
