[BUG] RouterLink is using RouteAlias value instead of Route value in 14.5.1

Describe the bug

A view class with a route something and a route alias "" (empty) was passed into RouterLink to create a router-link anchor.

Before 14.5.1, the href would be something, but after upgrading to 14.5.1, it has become empty. This is causing some of our BDD tests to fail.

This is only an issue when the RouteAlias value is empty. If the RouteAlias is a non-empty value, the routerlink uses the route value as expected.

To Reproduce Steps to reproduce the behavior:

1. Create a class as follow

@Route(value = "something", layout = MainLayout.class)
@RouteAlias(value = "", layout = MainLayout.class)
public class SomethingView extends VerticalLayout {
  /* some content */
}

1. Create a router link and use it on a view

RouterLink routerLink = new RouterLink(name, navigationTarget, parameter);

1. Check the href of the anchor

Expected behavior An anchor with something as href.

I was upgrading from 14.4.7 to 14.5.1

We’d like to update to 14.5 because of the security issue report

If you are using OSGi in your apps, I would recommend you to update to version 14.4.10 immediately to get the fix in use for your apps. This way you don’t have to wait for anything or make any changes.

I cannot give any promises to when this would be fixed exactly. As it is not a Severity: Blocker, it would not be urgent and assigned immediately unless prioritized by someone, but since it is regression, it is in the priority-queue after other prioritized issues.
