📚 Description

currently route.fullPath is / on server and http://localhost:3000/ on client. This implements same behaviour as on router, which also fixes an issue where baseURL wasn't being correctly handled with universal router:

	functioncreateCurrentLocation(
	base: string,
	location: Location
	): string{
	const{ pathname, search, hash }=location
	// allows hash bases like #, /#, #/, #!, #!/, /#!/, or even /folder#end
	consthashPos=base.indexOf('#')
	if(hashPos>-1){
	constslicePos=hash.includes(base.slice(hashPos))
	? base.slice(hashPos).length
	: 1
	letpathFromHash=hash.slice(slicePos)
	// prepend the starting slash to hash so the url starts with /#
	if(pathFromHash[0]!=='/'){pathFromHash='/'+pathFromHash}
	returnwithoutBase(pathFromHash,'')
	}
	constpath=withoutBase(pathname,base)
	returnpath+search+hash
	}
