The "Servers" drop down on a remote domain API-ML is incorrect on the Catalog page for that remote API-ML

[youngaaronm]

Describe the bug
The "Servers" drop down contains an incorrect value for a remote domain API-ML on the Catalog page for that remote API-ML gateway on the central API-ML catalog.

Steps to Reproduce

1. Configure at least two API-MLs. Configure the second API-ML to have an additional Registration to the first API-ML.
2. Logon to the Catalog on API-ML 1.
3. You should see an entry for the gateway for API-ML 1, plus an entry for the remote API-ML2.
4. If you select the remote gateway API-ML 2, look at the "Servers" drop down server url on the page.
5. You will see that the Servers box contains the value for API-ML 1, not API-ML 2 as expected.

Expected behavior
The "Servers" drop down box should contain an entry that points to the API-ML gateway for the entry selected.

Catalog UI updates swagger URL with "window" location. This works for most of the cases but does not count with additional GW.
