[4.x] Make URL::temporarySignedRoute() respect the bypass parameter (#1438)

Using `URL::temporarySignedRoute()` in tenant context with
`UrlGeneratorBootstrapper` enabled doesn't work the same as `route()`.
The bypass parameter doesn't actually bypass the route name prefixing.

`route()` is called in the `parent::temporarySignedRoute()` call, and
because the bypass parameter is removed before calling
`parent::temporarySignedRoute()`, the underlying `route()` call doesn't
get the bypass parameter and it ends up attempting to generate URL for a
route with the name prefixed with 'tenant.'.

This PR adds the bypass parameter back after `prepareRouteInputs()`, so
that `parent::temporarySignedRoute()` receives it, and the underlying
`route()` call respects it. Also added basic tests for the
`URL::temporarySignedRoute()` behavior (the new bypass parameter test
works as a regression test).
