Returns whether the given URL matches the current browser location.
Examples
location.hostname // => '/path'
up.history.isLocation('/path') // => true
up.history.isLocation('/path?query') // => false
up.history.isLocation('/path#hash') // => false
up.history.isLocation('/other') // => false
The given URL is normalized, so any URL string pointing to the browser location
will match:
location.hostname // => '/current-host'
location.pathname // => '/foo'
up.history.isLocation('/foo') // => true
up.history.isLocation('http://current-host/foo') // => true
up.history.isLocation('http://otgher-host/foo') // => false
