Please, fix the user's default tab after creating a new user

Steps to reproduce:

1. Open Users list, click on Create button (/#/users/create)
2. Enter user details and click on Save button
3. Observe broken default user tab with url encoded hash (/#/users/%40localpart%3Aexample.com), page reload does not help
4. Click on the User tab name, and observe working default user tab with not url encoded hash (/#/users/@localpart:example.com)

So, it looks like the problem is with url-encoded hash params
