Unexpected behavior when hash routing is enabled

[mlaadd]

When hash routing is enabled, on first page visit (or reload), it will return a different hashString as compared to when i normally navigate on the page through an href with data-navigo.

let router = new Navigo("/", { hash: true});
router.on({
"/": (params)=>{console.log(params);},
"/test": (params)=>{console.log(params);}
});
router.resolve();

for example:
on first load:
> example.com/#/test
< params.hashString is "/test"
on navigation through a link (data-navigo href="/test"):
> example.com/#/test
< params.hashString is ""

normally i would expect it to return "" on both occasions.

however if an "actual" hash is provided it works like that
on first load:
> example.com/#/test#test2
< params.hashString is "test2"
on navigation through a link (data-navigo href="/test#test2")::
> example.com/#/test#test2
< Navigo: "test2" didn't match any of the registered routes.

here i would expect them to return "test2"
