fix(common): Update Location to get a normalized URL valid in case a represented URL starts with the substring equals APP_BASE_HREF (#48394)

```ts
@NgModule({
  imports: [RouterModule.forRoot([{path: '/enigma', component: EnigmaComponent}])],
  providers: [{provide: APP_BASE_HREF, useValue: '/en'}]
})
export class AppModule {}
```

Navigating to `/enigma` will redirect to `/en/igma` not to `/en/enigma` as it expects

Fixes: #45744
