Incorrect routing path for duplicate page names

### Current Behavior

Hi guys,

It seems that some time ago I have created two pages with the same name:


This was not intended, because of course it makes no sense to have duplicate names in the dashboard menu.
Anyway it can also happen if you import a flow from a user to assist him with something...

Both menu items show up in my dashboard, but when you click them they both refer to the same path:


When I change one of the page names, the problem is immediately solved.

### Expected Behavior

I would expect that the correct path of each page is being used.

### Steps To Reproduce

Create two pages with the same name.

### Environment

- Dashboard version: v1.14.0
