Fixed: API not loaded the first time

[malincrist]

Problem

When navigating on a page that has API: Details widget, the first time the user selects an API (from the widget API: list for example), it is not loaded.
This is happening due to the order of the operations in the initialization flow: if there is no API in the URL initially we return without subscribing to onRouteChange(). Hence, even if the route changes, the API: Details widget doesn't react.

Solution

Subscribe to onRouteChange() even if there is no API in the URL.

Closes #2421
